SourceForge.Net RSS Feeds

I know that there has been some talk recently about the RSS feeds for projects hosted at SourceForge.Net but I also just discovered that there are some site wide RSS feeds as well.  Things like Site-wide news, Newly Registered Projects, Top Projects By Download and Top Projects By Activity to name a few.  You can find out about all their RSS here.  I need to stay up to date with projects going on there.  I always seem to forget about them, I guess because they don’t show up very much in google searches.
