Site to offer VG Skins to the public.

I’m looking to start a free template (video game characters) site where people make a template (skin) and upload it to the site with a picture, description (author, etc), and file.

Basically the front page would show the latest uploaded templates and offer categories. Is there a website template on themeforest that would support this?

You mean like WordPress. Magento. Joomla, etc…?
