Yeah, a few years ago many of the sign-up dates apparently were jumbled. The only reason I know mine is because I printed out a dated copy of my sign up info when I registered. The sign up date on my profile is about 10 months later, but that may reflect my first post. I am pretty sure I initially signed up to buy and sell stuff, and then started posting later.
It is good to see some of the old names on this thread. The culture seemed a bit different back then, but things in general were different, the internet was new, we still relied on B&M stores, a lot of DIY was new and untried, my budget was less, and people seemed more helpful than competitive, but those impressions may just be my rosy retrospection.
