I just sent a test-PM. Hopefully everything works fine

I'm quickly going over the usecases, and i wonder if i'd be able to make a feature request (if this feature is deemed usefull by other people aswell, and offcourse only if you're interested in programming it)?
I wonder if id would be usefull to add a destruct-code in the PM aswell? This way, you could send a first PM with a destruct code, if a deal falls trough the PM gets published... But if the deal goes fine, the initial sender can send a PM with the destruct code and the initial PM will be erased instead of published?
