Works great now *thumbsup*.
After I fixed the issue of cronjobs not running that is (occasional problem because of my host and the short timeout in wp) ^^

I have one thing to comment about though.
Should the feeds really be cached by default?
And if so shouldn’t they be cleared out when a new post is published just as the frontpage and blog page? I spent an hour troubleshooting today before I saw the cache footer in my feed…
It also seems like the caching kinda ruins the feedsmith plugin, but that may have been a one time thing.
