A couple of points:
1) I left Poppitz in because only a few of his pieces looked copied, we talked about it, and he was not going to do that again. I sent in the work as part of the avatar bounty as examples of his work. As I understood it, entrants were to send in 10 pieces, even if all 10 of them don't work, they were to be sent in. Fenrir was a different case. All of his work was directly stolen. Poppitz just drew by hand from examples on the internet. Fenrir was also unable to demonstrate an ability to draw his own work.
2.) Burns and Poppitz' avatars are some that I sent in for fun last Halloween (A year ago)and told Mur and everyone on the forums that they were Freddy and Jason. I even named them that, Freddy.jpg and Jason.jpg, when I sent them in. I also sent in an image of a spartan that I'd drawn from an image on the internet with that same batch. Someone pointed out the copyright issues involved, which I hadn't thought about and I haven't done it since.
3.) People leave messages on the Forum all the time, some with decent artwork, but it stated clearly that they were supposed to send email to glordamar@gmail.com. There was also a period of time where I couldn't check the forums daily or even much more than weekly and I know I missed a few people. I'm sorry for that, but many of those that I did contact were either unable to continually produce high-quality art due to talent or equipment (scanner, etc.) or couldn't seem to grasp the requirements for artwork submission. I had a lot of trouble finding people who were both talented and able to do the job.
If there are others that I can think of I'll put them up too.
