But i think it should be implemented into the game, but only with clans, you can only PM your clan members, and if you leave the clan, you cannot PM them.
so basically you can ONLY PM your Current Clan Members.
THIS WILL NOT LEAD TO BULLYING OR ABUSE, if someone dont like the clan, they leave and no1 can message them and they cant message the clan, it works for me, what do you guys think!!!
