We do have plans to implement RSS feeds when we finally upgrade to the latest newest version of the forum software.
I'm not too sure when I'll finally do the upgrade, though. I initially postponed it because I wasn't happy with the new version of the software when it was initially released. It was buggy, and I knew they would be releasing another upgrade shortly after that, which they did. Now, they're getting set to release yet another upgrade.
The new version still has some changed features that I'm not entirely happy with (like a new post screen that is not very user-friendly in my opinion). So, uhh... I don't really have a good answer as to when we'll have good RSS support beyond "when I think there are enough new features to warrant the dozens of hours it's going to take to recode the entire site."
