Joss Winn has an excellent post all about feeds in WordPress for anyone interested in this kind of thing. One of the things I realized yesterday was that WordPress does have a feed for individual authors within a group post, I don’t know how I missed this up and until now, but I did. To quote Joss:
There is a feed for each author of the bloghttp://example.com/author/joss/feed
This really changes the way I imagine group blogs now, and the ability of students and faculty to quickly republish there posts from this space into another becomes trivial, very, very cool! Luke Waltzer and I tested this out as he plans on taking 58 posts he wrote in the cac.ophony blog and re-publishing them within his own space that is coming soon, and it worked without a hitch (well, at least it did once we copied the rss.php and rss-functions.php files from FeedWordPress in wp-includes directory)! Here is the construction of the feed we pulled from: http://cac.ophony.org/author/luke/feed
The only little trick is that you have to change the “Syndication feeds show the most recent” field in Settings–>Reading from 10 to something that will catch all the posts you create in a blog, for example Luke put his up to 100 which easily got all his 58 posts out.
