Drat. I apologize.
I never switch privacy nyms on purpose in the same thread.

My vpn scripts that Marek mostly wrote somehow didn't like,
I think, that I moved from Linux to Windows just now, posting from both
(where it keeps a variable based on the subject line), so something
didn't reset (a bug in those scripts somewhere as my long time Usenet
reader is "vi" and the randomizer scripts use telnet to the nntp server).

o The Windows 10 on HDD1 (WD10EFRX, sdc)
