wordpress capabilities

Hi,

I’m new to CMS stuff. I need to know of wordpress can meet all my requirements. I’d like to have the same functionality as found at:

http://www.codeproject.com

I want users to be able to submit articles with a file attachement which are then automatically published (or if auto publishing is not possible, I should be able to create a new article space for it on the site). Once the article is posted, I’d like other users to be able to download any attachments, and rate the article, and post reply comments to it.

Here is an example article on their site:

Can wordpress do this?

Thanks,
Mark
