There should be a lock-posting-except-for-Participants button. Like for the Test Forums, for example. I don't mind knowing people can read|look at my testing of eloquence. I've seen the option to post a comment in other Peoples Test Forum areas. That should be negated.

I second this. It'd be nice for RPs and test threads.

However, I think the idea could be adjusted. If you're including just "participants", that would include whoever has posted in the thread regardless if they are an active player, poster, w/e. I think it would be better if the idea was retooled into a sort of "reverse banning", where you could input certain usernames that are allowed to post. It'd require the 10 people limit to be removed (or updated to, IDK, 999999999 or something) for larger groups if we're going to use it as a reference point, though.
