Yeah basically as DK said. Caddis was involved in the original source of the name and where plus613 stemmed from, but he had never had anything to do with the site.
This site was simply a coding exercise for revert, to start with it was a simple page that displayed one random image. That was it. I helped with the running and the original batches of images, DK came in to help coding and then revert lost interest and disappeared. Well, not disappeared, but as far as the sites are concerned he did. He was already dropping out but at the time of the porn split he basically lost interest totally.
And then plus613 1.0 was launched. It was, if any of you remember the site and were around then, basically the same except it had no image commenting and just a very basic rating system. Then came image comments and the forum, then it was all redone again properly and now it's the site you see. And that's more or less where development was left
Ideally I should update the about page, it hasn't been touched for a couple of years. And hey, that means the site is 5 years old at the end of the year. Scary.
