I guess when I look at my profile and view all my posts, they don't go as far back as when I joined.

I joined back in 2003 (I can't believe it has been that long!). I had lurked around a bit before that when I got Jane's 688i Hunter-Killer. I remember downloading a patch for it off Subsim. Anywho, what got me to sign up and register was a contest for Dangerous Waters or SH3 I believe. I don't remember which sim it was (or maybe Sub Command). All I had to do was post in the thread to be entered for a chance to win the game and I think the devs would sign it. I probably got the contest bit all wrong by now, but that is the gist of it.
