What I mean is not really room to show the topics and posts seperately, since you'd have to indicate what each number was for.
Say you have 3 subforums. You really don't want it to look like:
Subforum 1: 1 topic, 2 posts Subforum 2: 5 topics, 8 posts.
That would seem to be a bit much. It would probably look a bit better if it was just:
Subforum 1: 3, Subforum 2: 13
