Hi Purus if at possible could you make it so the admin can add a number of names that can be selected to be sender of the pm.
Then the site could pick a name from the list and send the pm in order of the names listed. When it reaches the last name it simply starts from the begining.
It would also be a big improvement if the the name selected from the list of choices given by the admin could then be automacticly made into a friend.
Thanks
Shaun.
