Well looking back at some postings from '99 I don't see any usernames that are regularly in current use, not to say that the same
users aren't still around though

Welcome to PPRuNe
PPRuNe Bulletin Board
I see the mods listed as ULURU and Southern Comfort, neither of whom appear in the present user list...
