Damn, you made me look up my join date. May 21, 2007. I also looked up my original registration email from DT.net: March 23, 2006. I thought it was April 2006, after going to the Score show, but I guess it was before. As I remember it I couldn't get anyone to go with me, and I needed someone to get excited with, so I joined. I remember one morning trying to log in and the forum was gone. I have no idea how I found this site (which had another schism soon after resulting in fiveeight forums??), since I don't know if there was a forwarding link. I may have just googled and saw some familiar names.
In those years I've had a similar feeling to many here, in that it was an outlet of diverse ideas that I hadn't encountered much in my offline life and contributed to much of my personal growth.
I've not been super active here, especially in the last year or so since the site has been blocked by my company's firewall, and have only met a handful of members here in person, but I appreciate the community here nonetheless.
