I think the limit should be raised if possible, would make things easier for me. I don't like deleting some PMs and my box is almost always full.
Seriously, how many people actually want to PM you? Or anyone? What, is there some secret conspiracy I'm not aware of?
I've gotten 20. One half are double posting warnings from Chelsea the other half are from the Hexagonal War Thread.
Those were old for anyone who is wondering. One thing that I do agree is a bit much, users are required to be informed twice for each official warning. First the warning automatically sends them a PM, then we are required to send one ourselves.
