Ok, I uploaded one sometime before I got any of your responses. How long before I hear back on the upload then see it posted on the site? I have many more, also.
There is nothing showing in the moderation queue for your user nick.
What gallery section did you upload it to?

Answers about the Moderation Process
We have been receiving some questions about moderation from both new and established users. I wanted to take a few moments to answer some of the common questions, and give you a chance to ask questions that I will answer in a later post.
Why was my skin approved later than others, even though I submitted before them?
Skins are not moderated in order of their submission. Once a skin is uploaded it is placed in a moderation gallery to be looked at by the moderators. Some skins take longer for a variety of reasons such as waiting to receive more opinions on the skin, or to verify a permission, etc. We try to get skins through as fast as possible, but we have a limited staff, and although they do phenomenal work, only so much can be done at a time.
