:) Thanks Ken and Dave.

I guess you figured it out. Last I knew, you and Larry didn't even
know if this would be possible ;)

Hmm . . . This would be fine for me, but maybe someone else would run
into a problem with wanting to use '/' in a username (have no clue
why). In that case, an entry like "usesep: whatever_char_here" might
be a better idea, although admittedly harder to implement.

Oh, I will :)
Thanks a lot Ken. I've been using Dave's patches quite successfully
(thanks Dave), but was looking to see them implemented with your ANN.
