I joined Skinbase in 2003. At that time I don't recall seeing a bunch of pop ups.
The site wasn't getting an outlandish amount of activity back then and, well, I kind of forgot about the place....
Anyway, until I remembered that I was a member I was experiencing a completely intollerable amount of ads, pop ups, crashes, etc. I understand the need, but the extreme that has been chosen is so counter productive it isn't funny.
