What you are looking at right now is OpenGameArt.org version 1.5 (or most of it, anyway -- there are a couple things I'll be adding over the weekend). The site should (hopefully) be relatively usable and intuitive at this point, and you should be able to do everything you could do back in version 1.0. If you run into any problems with anything (posting on the forums, commenting, submitting art, etc), leave a comment here, or drop in on our IRC channel:
