An edit function would be cool, so you can correct mistakes after you've
hit send.

The reason for there not being one is because it's linked through to
e-mail where once a message has been sent it's not possible to change
it.

If you screw up too badly then messages can be withdrawn – there should
be a withdraw button underneath your own messages when you view them
individually.
