I don't know if this is hard or not but I'd like the ability to tag people in a post, preferable coming up as a notification on the site. It's not something I'd use all the time but I'd like to tag certain people to some post to make sure they read it. This could come in handy for army updates posted by field marshals to make sure all their officers have read it, or a squad leader posting thread and making sure one of his members reads it.
It has the possibility to be abused but I think it would be a cool little feature.
