Also, I'd like to see a feature from hackforums added as well if its not too difficult. (it's a mybb mod found here

If a post has been reported, do not allow other members to report it again.
I've seen this mod by BoP but I'm sure it can be abused by clever members who paste the report url + showpost # into a new window.
