I really support the personal/private message idea. It's not a big deal how it's implemented, as long as we can send other players offline messages. Add whatever settings you want, but I'd love to carry on a conversation once a week/month with people I don't align schedules with or tell my old friends that I'm back without waiting for them to log on. I don't want to be that creepy person and google people's names and find their facebook and say "hey it's me from runescape! Lol remember me?" or have to find another platform. Lesson learned from skype.
