I realized that you cant send a private message to someone. the only way is to leave it on the comment box, and sometimes there are things i jsut wana talk about with say a friend, and it gives personal information, etc. So, there should be like a message box sort of thing. Just throwing that out there.
For now, we are going to stick to the normal messaging system. It has been a suggestion made quite a few times before, so we do have it on our suggestions list.
