In the case of parent-subforums, where you've made a feedburner feed that aggregates all of a set of subforums (/external.php?type=RSS2&forumids=3,4,5,6)....I can't see how the above will work with your code modification to display one feedburner feed for all 4 of the forums. In your second to last line:
Code:
href="http://feeds.feedburner.com/yourforumurlcom-$foruminfo[forumid]" />
That won't work, right? If you've done what I described above (aggregating with forumids=3,4,5,6, and creating a feedburner feed of that)...your modification will break when it generates the link above....as the feedburner link will be
http://feeds.feedburner.com/yourforumurlcom-3456 if you left the default.
For example, you're viewing forumid=5, your code above generates a link to
http://feeds.feedburner.com/yourforumurlcom-5 for which there is no separate feedburner feed....
ack I'm so confused.
