I had an account that I forgot all about made a few years back just to look around. I think I only browsed for a day or two because I wasn't really buying online at that point.
I signed up here last year and started posting in the forums and writing reviews within a day or two. I found out I had that old account because I use a similar screen name for most things and managed to accidentally sign into the old account once.
It didn't take me long to get involved. Part of the reason I signed up here was to do the review program, not just to buy things. I was doing makeup reviews at the time and sex toy reviews sounded like a lot more fun.
