Great point. I uploaded a right click Chrismas skin yesterday. It came back saying I needed permission to use other peoples graphics. All the graphics I made and would never think of using someone else's. I submitted it again with a permission txt in it. This was so someone would look at it. I asked to be advised what rules I have broken as I made all the graphics. I'm really lost here as I did nothing wrong except to make something for the community.
I think it was missed the second time because it came back on the same calendar day and a different Mod (probably me) assumed it still needed an email because the original moderator forgot to note that he had sent you the first email. The snafu has been sorted and the skin is in the library.
Just to add to ID's post...if you include a note in the comments that all graphics are original or that permission text is included then it makes it easier for the Moderator to do his job.
