Well, my boss, who's braver than I am when I get strange email's, jumped out to the link provided on the "welcome to adepters" email we all got (or are getting). What it looks like is Arbortext has moved the Adepters Archive out of the Support page and put it out where we can access it easier (sic). I tried going to the archive through the support link and got taken to the new page.
Right now, it seems as if a goodly percentage of the older messages are missing, the search function is non existent (a search for 'Lynn' returns nothing found [maybe there's a message there]), the most recent archive entry is 2004 (at least when I went there).
Hopefully we'll hear just what this is supposed to do for us. But for right now, it doesn't seem to have impacted the group itself.
