Can't delete own posts?
 

I just posted the same thing twice in a thread by accident and realised that I get an "access denied" error when trying to delete the excess post.

Any reason why?

Users cannot delete their own posts. If you need a post of yours deleted because it's a duplicate or for some other reason, use the report this post to moderator function on that post and simply explain why you need/want it deleted.

As to why and any further information, see either of these threads:
