Bug! Discussion and deleting posts!
I was testing out some things on my forum. I discovered that when I deleted a post and visit the home page discussions list, the discussion I deleted the post from was on the bottom. It said "most recent by __" and it had a blank space there. Seems like a bug. If it is a bug, then it should be fixed so that when moderators delete a post, the discussion should be in the place it should be.
