Can you give us a feature list for this upload site? Specifically:
Will registration be required? In other words, will the site be protected behind a login and password?
What kinds of files will be uploaded?
Will the site also offer the uploaded files for download?
If so, what format will that be in? Will you require file search capabilities?
Please list all the features you expect to see.
Perhaps if you gave an example of a website you are looking to emulate...
