Allow members to junk/close/delete own threads & posts.

[D3xus]

I understand junking/deleting their own posts, Omni.
But I don't think allowing a member to close their own thread (maybe in specific subforums where it could have legitimate usage) is out of the question.
So if someone in the Emotional Help subforum wanted to close their own thread when they had received help, that would be an example.
