add a delete button to @mention wall

I have a question, the plugin works really great, thanks for that, I only miss the option that users cann delete the post on their @mentions page. If i give them administrator rights it works great but then they can also delete the items on an other wall. Can someone help me to what I have to change so they can only delete their own post and their reveiced mentions?

When someone wants to watch I can add an demo account

(forgive me for my bad englisch)

Thanks.
