Nice little hack, really inventive idea.

Our only concern is how quickly it fills up, that's 2 wipes in like 30 minutes!!
You have any intention of coding it so after 'x' messages it deletes itself?
Or if can't be assed to code it, any chance of being able to give a group perms to wipe it? Right now from what I Can see I would have to make somebody a full admin with all the rights that gives just so they can wipe the wall.
Is it possible even to code it to a specific person or group ideally so they can view the wipe button?
