Forum Software Upgraded

I cannot delete messages no matter what I try. The website is missing buttons or something for the delete function. Since it's saying I am maxed out at 15 messages (which I didn't know about) I have to delete some of them. Also, I am seeing way way too many popup ads that are quite annoying.
