Nobody noticed. No need to have Word, or any other app, incorporate PDF conversion to output a PDF file. Use any PDF printer emulator you want. ANY app that has a Print function can output to a .pdf file. I currently use Bullzip PDF Printer, but I've used PDFCreator in the past. There are lots of PDF printer emulators aka virtual printer software. Some are listed at: https://en.wikipedia.org/wiki/List_o...are#Creators_3 https://en.wikipedia.org/wiki/List_o...inter_software |

No. They provide a web page with a login and tools, and they provide Gmail for groups. So, her files could be stored ANYWHERE when she uses that web page to download and upload the files. |

Problem solved. :-P Even more stupid are gov't agencies that demand use of faxing to transfer sensitive documents. They don't trust e-mail despite e-mail certificates provide security; however, rare few users install an e-mail certificate for use with their local e-mail program. Encrypted e-mail is by invite: the one (recipient) wanting to get encrypted emails has to digitally sign an invite e-mail (by adding their digital signature to an outbound e-mail), the other party has to store that public half of the sender's certificate (in the digital signature), the other party then uses that public cert to encrypt their e-mails back to the first party, and the first party (that did the invite with their public half of their cert) is the only one that has the private half of their cert to decrypt the encrypted message. With the diminishing sources to get free e-mail certificates, having do to the setup, remembering to digitally sign their e-mails to those they are inviting to send encrypted e-mails back is too much setup for most e-mailers to bother with; however, it is very possible to setup encrypted e-mails between any sender (that gets the public half of the cert) and a recipient (the only one with the private half of the cert). How many users do you know that have configured their e-mail program to do encrypted messaging? Gov't boobs figure e-mail is insecure because that's the default mode of transmission: unencrypted. Faxing is even less secure than e-mail: (1) the transmission is NOT encrypted, but sent in the clear, so anyone intercepting the transmission can read it; and, (2) the fax sits around in the fax machine's output hopper at work where anyone walking by can read it instead of the specified recipient (fax machines are shared at work, not a unique one on every worker's desk). Yes, there are encrypted fax machines, but they must be used at both endpoints in the transmission, and that rarely happens except between businesses or gov't agencies that have established secure faxing between themselves. That is, encrypted faxing is an interdepartmental thing, not something users bother with, especially since they aren't going to pay for a fax machine that encrypts. |

(fax machines are shared at work, not a unique one on every worker's desk). not always. it depends how big the company and individual departments. |

The new laptop came with a print to PDF printer already defined. I did not try to see what happens to an URL in such a conversion: is it clickable in the PDF? -- Cheers, Carlos. |

The "even more stupid" could be endless :-p They don't trust e-mail despite e-mail certificates provide security; however, rare few users install an e-mail certificate for use with their local e-mail program. Ufff (I don't know if that translates to English Ok) Yes, I once tried to send/receive encrypted email with a lawyer. Was a no go. He did not manage to set it up. Encrypted e-mail is by invite: the one (recipient) wanting to get encrypted emails has to digitally sign an invite e-mail (by adding their digital signature to an outbound e-mail), the other party has to store that public half of the sender's certificate (in the digital signature), the other party then uses that public cert to encrypt their e-mails back to the first party, and the first party (that did the invite with their public half of their cert) is the only one that has the private half of their cert to decrypt the encrypted message. With the diminishing sources to get free e-mail certificates, Hum. In Spain almost anyone that does internet things with the government, such as filling the tax form, has a certificate issued by the "Royal Mint" that is legally binding. Fewer people know that if you copy the certificate from Firefox to Thunderbird (for instance) we can sign and encrypt emails. Also, our National Identity Card (a plastic card that fully identifies a citizen) has a chip that can be used for electronic certification of ID, and perhaps to send encrypted email. However, there was a security problem and the batches for several years of cards had to be voided for electronic use. having do to the setup, remembering to digitally sign their e-mails to those they are inviting to send encrypted e-mails back is too much setup for most e-mailers to bother with; however, it is very possible to setup encrypted e-mails between any sender (that gets the public half of the cert) and a recipient (the only one with the private half of the cert). How many users do you know that have configured their e-mail program to do encrypted messaging? Gov't boobs figure e-mail is insecure because that's the default mode of transmission: unencrypted. Right. I suspect, though, that email sent and received within the same "Gmail for Groups" platform is somewhat secure. For some meaning of the word. Probably the sender can be verified, depending on what method the group administrator uses to give addresses. If the email goes outside of the group to another group, or to Internet, things change. Faxing is even less secure than e-mail: (1) the transmission is NOT encrypted, but sent in the clear, so anyone intercepting the transmission can read it; Quite so, although illegal. ;-) and, (2) the fax sits around in the fax machine's output hopper at work where anyone walking by can read it instead of the specified recipient (fax machines are shared at work, not a unique one on every worker's desk). Yes, there are encrypted fax machines, but they must be used at both endpoints in the transmission, and that rarely happens except between businesses or gov't agencies that have established secure faxing between themselves. That is, encrypted faxing is an interdepartmental thing, not something users bother with, especially since they aren't going to pay for a fax machine that encrypts. I've never seen encrypted fax. :-o -- Cheers, Carlos. |

The phone line can be connected to at any point in the route, and the Telco exchanges can do a virtual connection (which is what government agencies or the police do). The digital stream can then be stored as a file. -- Cheers, Carlos. |

Not anywhere, but at the facilities provided by the employer IT services that provide that page. And being https, the transmission is encrypted. Of course, people can also store the files anywhere, if they can be downloaded to local file. -- Cheers, Carlos. |

It's very easy to download, install and use, so you can explain how to do it to her over the phone. Do the same on your computer. Once it's installed on both, you use TeamViewer to show her how to do it while you're explaining it over the telephone. -- Ken |

On the new computer I installed it myself, then demonstrated it. By the way: it displays some kind of permanent banner on the bottom left. If I click to close the banner, the session dies. Is it possible to remove it? Then it always seem to ask (on windows) to buy it. On Linux it doesn't ask that much. And it remains running as a applet, which has to be closed manually. -- Cheers, Carlos. |
