Delete Forum Posts

Can members delete their own forum posts?

I get asked to delete forum posts all the time and I can only see a setting for members to be able to 'delete all forum posts'

From looking at my test site - YES members can delete their own posts. Not to sound rude or anything - but it is right there on the page. Now, I am not sure if this is only allowable for a certain period of time, but I just created a new topic and it is deletable, and a new reply to an existing topic - also deletable.

My fault. I did not have 'forum del topics' enabled in membership levels! Doh!
