having just received a hostile PM from a memeber i've never heard of, i would like to request a "whitelist" feature: the ability to block PMs from everyone except those people i've approved to send me PMs.
adding someone to one's "friends" list should automatically add them to one's whitelist, but one should also be able to add a person to the whitelist without making them a "friend".
