Q. What is the number of posts I need before I can PM?
A. It changes based on current need/problems, but you are safe around 100 posts, but if you upgrade then it is much less - see the Compare Page.
Q. I keep getting messages saying that my inbox is full, but I only have a couple of messages in there!
A. PM is not meant to replace your Email, it is a means to make intitial contact only and then you can exchange Email or I'm addresses as the case may be. Therefore, your inbox has limited storage which means you will have to delete old messages often. Please ensure that your sent folder is not also storing messages.
Q. Someone sent me a bad PM, should I report it?
A. Yes! Rules are to be followed even in PMing. Use the contact page.
