I do have an online comic myself, two in fact, although I never get to work on them anymore because of all the modeling I do now, and except for doing promos and WIP renders I don't really post on line either. I do like to collect a lot of stuff though because you never know when you'll need it.

Just checked with CP about selling and they're not taking new sellers at this time. Of course, I wasn't planning to sell at this time anyway.
