31 now... but I'm working on a better content submission system. Basically, the new system is an AJAX system where you select the category you want to submit to, and it automatically adjusts the form to prompt for the relevant information for that category (this includes a file upload field depending on the category). When you submit the content, it's sent to a "review panel" that I can access via a web interface, and I can approve/disapprove submissions. Once approved, they automatically appear in the right section.
You shouldn't expect this full system to be rolled out until Summer 2009-- but it's in the works. I think it'll encourage more community contributions.
