This website isn't new, but I just rewrote the whole thing with Yii. Previously is did not use a framework, but had very linear code.
Tell me what you think, and report bugs.
PS. oh yeah and right now you can not actually upload/contribute. I have not re-written that part, partially because no one was really using that feature anyways.
Some pages may seem slow the first time you view them as the thumbnails are not generated yet (they generate as they are needed).
I rewrote it as I am in spring break and felt like it, but my spring break is over and now I wish I did something else. If anyone is curious it makes about $130/year in adsense (yeahhhh…).
