You can't remove topics
Yes you can, it's to the left of the lock topic button.
I just removed my thread about how the crocodile hunter died, as a mod you can probably view this, it's in the deleted posts board:http://dplogin.com/forums/index.php?topic=3242.0
Oy. I can't believe I missed that so many times. There is a separate permission for removing topics. It isn't covered by disabling the delete post permissions. SMF has too many options, sometimes.
Fixed?
