Quite a while ago Hugh Sasse asked if an individual RubyForge project news page could have an RSS feed. That capability was built into GForge, but I couldn't figure out how to get Firefox to surface it. Hugh had posted a suggestion, but it slipped off my radar for a while.
Anyhow, I added the code he suggested and lo and behold, there it is. So now if you go to, say, the Ruby Windows installer project news page and click on the orange RSS icon in your Firefox address bar, it'll give you two options. Pick the second one and that'll be the project news feed. Huzzah!
I'm still not sure how to twiddle that link tag so that it shows a different name for each feed - when I change the "title" attribute to anything other than "RSS" it seems to confuse Firefox. Suggestions welcome. Update: Hugh suggested a fix, it worked fine, now the feeds are properly labelled. Thanks Hugh!
