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

[AceInfinity]

I would agree with Fragma on this one. If you pay attention to what you post then there's no real difficulty that would force you to want to delete anything, you can just edit the parts you don't like. I've never felt the need to remove anything other than a spam thread or spam post by a spammer on a forum, but as far as my own posts and threads, never.

Closing would be useful though, especially for solved threads on specific member issues.
