A few days ago it went from being 94% full to 100% (didn't even get a new PM), so I deleted some sent messages, it didn't work, which it did I think once or twice before (I THINK I deleted sent messages). I deleted a couple or so received messages and it's still at 100%. That's why I couldn't send my PM response to you about being a Super Moderator. I don't want to delete my received PMs. What can be done?
