I'm registered on jeepboard.com since May of 2003, but I never post there anymore. I got tired of the predominant pro-war and ultra-conservative mindset of the vast majority of the people who frequent those boards.
I used to hang out on pirate4x4.com back then too, but I never posted much. Those guys on that board were ruthless. Not a really nice crowd, and hard on newbies.
I think I registered on jeepforum too at one time, but dang if I can remember what my user name and password were.
