This is going to be a quick topic, though it should be longer, for lack of time.
I've recently started a few threads that are a bit more geared for older, and more mature forums members, so I usually have to use caution and make it known that jokers, spammers, and friends are not tolerated in the thread. They usually still come in and wreck the topic either unintentionally or intentionally, doesn't really matter. So what I'm asking for is the ability to 'moderate' threads that you create.
This would include 'muting' people so that they can read but not post in the thread, as well as the ability to delete or hide posts that are made inside the thread. This would allow the forum to have more on-track discussions and prevent a lot of drama.
Obviously this shouldn't be abuse-able, just to keep certain people out of the thread, so I would think that as the same as PM, your moderation permissions can be taken away for however long/permanent.
Just a quick thought, anyone go ahead and discuss your feelings as well.
