I almost selected that I don't remember. I joined back in 2006 (under my Divin'Hoosier account) and that was before I was on Facebook. I didn't know any other ScubaBoard members personally at the time so it had to be from a Google search. I'm a huge "Googler" and was way back in 2006. I have very little doubt that I stumbled upon it from doing Google searches shortly after getting certified as I was craving as much data as possible on equipment and further training.
