Maybe the most stupid question, but..i can't go out of this.
I have a WordpressMu rss feed.
I can filter it by tag "mickey" using the following address: http://mysite.it/blogname/tag/mickey/feed
but if the tag is "mickey mouse" i have a problem:
http://mysite.it/blogname/tag/mickey mouse/feed seems to not exist, and i don't know how to filter my feed if the tag is formed by more that one word.
It can be a not MU question, but i assure you that it's important, expecially cause i'm using the Donncha sitewide feed for sending Mu contents to my homepage.
