Specifics:
- Either use the existing Foe list and just combine into the control for who can send you PMs
- Or have a separate list to control the in-game PMs only.
This will improve the following aspects of the site:
it seems strange that you can block them in in-game chat, but unless you want to stop all correspondance, then you have to accept that some idiots will send you a continuous stream of unnecessarily rude PMs.
Generally the cause of these seems to be ratings or responses to ratings, or taking a good beating in a game

the change will allow people to get the most out of CC without being put off the game by the mindless, abusive minority, who seem to be growing in numbers over time, because they CAN get away with it.
