My suggestions are pretty lame but here goes. Would you be able to add a function to delete your own posts? And maybe add a visitor counter of some sort and see how fast it climbs. You know what I mean..
We use apache to log how many visitors we have, a public counter probably isn't going to happen. Deleting your own posts isn't going to happen either, would make threads impossible to read if a user decided to delete a comment they said earlier.
How about a delete comment within 5 mins, cause sometimes it would be like... oh man, that actually didn't make sense. So you have 5 mins to change it before it stays there?
I think the 5 Min limit is within the game comments only. On the forum section you are able to edit/modify your comments/replies.
Game comments are editable for 5 minutes as of posting yes, forum posts are editable for as long as they're not deleted.
I still don't see whats wrong with being able to delete your post if its the last post of the thread. So you can go like 'you know what, this comment is spam *delete*'
