We have changed categories on the downloads section. The listing [on the menu] is now dynamically generated based on categories which have files for whatever game it is you are viewing. This also means you can now submit files for any game, in any of the categories.
In the next week or two we plan to add additional category support allowing you to select multiple categories for your file (the tentative limit is 3).
We also just launched our new "Events" portal, which will contain coverage, by us, and our users, for various gaming events. It currently holds the Blizzcon content from the website, which we will be adding a LOT to over the weekend during the event.
If you're interested in adding content to it, just tag your stuff with "blizzcon" and "2007" and it will automatically aggregate them. We plan to add submission forms on the various tabs later which do this automatically for you.
