I actually signed up YEARS ago. I think it was during the first or second year Gaia was around. All I know is, the site was majorly different to what is now and you didn't have all the handy-dandy different poses as you do now. There was also that little match-maker" thing that was going on for a while, but I remember that leading to all kinds of creepers popping up and it got super uncomfortable for a young teen.
Also, back then, it was WAY more anime than it is now.
But, I can no longer get into that old account, so I signed back up here this past summer.
