The plugin is restricted to mods only because of abuse. Way back when I would get so many messages in my mailbox about greifs and bridges I had no idea how to handle it all myself because people would automatically message the mod they liked the most. Not only that, but people would mail adverts to players instead of through the /m system becauae mods couldnt see mail. It opens a lot of doors for advertisers and bridge teams/greif teams to do things under our radar. It's just not a good idea. Use skype if you honestly want to be so private.

 

Yes, I've used that kind of mail system, and I think it would help.
