[MOD request]
 

Is it possible to have a modification to the PM system so a user can edit or recall a sent PM if the receiving user has not yet read that PM?

Its a common mistake to hit the send button when you meant to hit the preview button or you thought of something else to say/change, but it was too late since the PM was sent already.

This would be a good addition to the VBulletin system if it is not too much trouble to impliment such options without causing any bugs to the current system.:)
