Frank,

As he says himself, his style and MO is rather easy to recognize.

Sorry, but I'm simply not that good I'm afraid. Might be because I need a
bit more than "most likely", as I would not like it in the least if some
unsuspecting newbie gets caught by it.

But to be fair, of late he doesn't nymshift that often.

Hmmm. The first post of Arlen that I can see (in windowsxp) is of june 8.
Before that Ragunussen Ultred and (march 16, may 3), mike (april 29, may 29)
and Ultred Ragnussen (feb 14, march 8). (and that is as far as I can look
back). Either he took a month off here and there, or I missed a few.

The above seems to show he uses a montly cycle, although he also mentioned
he keeps his nym until a thread ends. Which ofcourse he just did himself
(making it exactly another month).

Regards,
Rudy Wieser
