Here. I think you could do with reading this for a start :

And on the point, I really don't see the problem with someone writing a comment on an old dare or truth thread. They still have the right to post.
I think the same applies for TorD online. People should still be able to post truth and dare for people if the OP hasn't said that they want the thread closing.
In the Slave/Master area, I wouldn't really class an ad from two weeks ago as old. Maybe they hadn't found anyone that appeals to them yet. I think that the OP just needs to report the thread to be closed once they have finished with it.
