The Sourceforge pages hold the public trackers (bugs, patches, feature requests), Plugins and Skins. The user forums are also there and the downloads. It also provides access to the public SVN repository.

Comments about each part:

The trackers have lots of reports, many of them should be closed as they are related to fixed problems or are duplicate of another ones. Cleaning Sourceforge Trackers?

The Plugins and Skins should have higher visibility so new users (and not so new) can see how to extend the browser and avoid frustration.

I think that there is already some thoughts about moving the user forums out of Sourceforge.

The Downloads are fine.
