I've had this happen twice. I've gotten a little message when trying to send a PM to someone that says their inbox is full and can't recieve any new messages. This thread (hope it's in the right place!) is for people to tell other people that their PM boxes are full because I don't know if the reciever knows it. Here's how it works: Person A tries to send PM to Person B. Person A gets a message that says Person B's inbox is full. Person A comes here. Person A says: "Person B, Your Inbox is full, please clean it out immediatly." Person B says: " Posted by: Person A "Person B, Your Inbox is full, please clean it out immediatly." Cleaned out!" Hope this helps someone.
