I've worked on adding some feed links for individual forums and even individual thread tags - you can get to them by clicking onto a forum page or thread icon page and then finding our RSS feed from there.
(Some may be missing now, but they should fill in as we go - hopefully. If you want to subscribe to one and it isn't there, please contact me with the forum or tag name and I'll figure out if anything's buggy with the new code)
Yeah, that's my fault. I made some changes last night and missed a couple of things. I got smacked by the server this morning and fixed it up, so it'll right itself tonight at midnight. ... Adam // edit: There... I ran it for today.
