Lost of forums seem to have off-topic posts, meaningless posts, and posts so old, they are no longer relevant.
Even this fomrum of suggestions for the forums.
I would suggest that the forum administrator could remove a lot of this clutter, by deleting off-topic posts a month after they were posted (or even earlier). ALternatively, if the moderator posts a reply anyway, how about just marking the topic of the post
OFF-TOPIC, so one doesn't waste time following the topic.
I would also suggest that you cull forums of posts that simply do not add anything, like "hear hear" type of posts.
