For this experiencing issues with PM system please make sure you have not filled you inbox, you can check how full you inbox is by going to your pms and on the right just above the pm it will tell you how full your inbox is.
Mr T I did look at my mailbox and neither one of them outbox or inbox are close to being full. So whatever is causing my missed messages, it's not that's its full.
Based on what I have heard, it sounds like small issues in each account or could be on an individual message basis. I know most of my messages have gone through but I know of a few that did not. And a few that I didn't get.
None of my boxes are full. I know I have maybe six or seven that have never been read. Those are the ones I send out to see if I could get in touch with older members. But that one is only at like 15% capacity.
The ones that seem to be the issue with my account is the ones coming in but I am aware of at least one message that was not received. I also know when I get a new message, the number on my account bar in the upper left never changes. It always shows zero.
