It's my 25th anniversary!

I have no idea when I first joined, but I have proof it had to have been in 1999 or earlier:

I found the column in an under-ground newspaper in Chicago. Was on the boards a little bit on AOL; signed up when they moved off. Wasn’t as active as some (most), but stopped for a number of years because the boards were too damned busy. Came back pre-COVID with a new logon.
