My profile states I joined in 2005, but I recall joining much earlier (or at least lurking since 2000 or so) and spending far too much time reading through posts on the main site and in the forums when I should have been working (ahem). Eric Noah's site (and now EN World) have been my main go-to for D&D related information (even though I seldom play D&D anymore) and one I still lurk on at least once a week (if not more).
Thanks, Eric, for starting this up in the first place, and thanks to Russ for keeping it going.
