It would be extremely helpful if we had the ability to start a post on the forums, and then delete them once they are no longer needed. For example, if I created a post looking to get a raid group together. Once the group is full, I could delete the post. Saves you space on your servers, and keeps the forums less cluttered. Obviously we wouldn't have the ability to remove everything, just what we type in a comment or the entire topic itself once it's complete (like the example above). I hope to see this soon.
