Invisible PM's

[Redhawk]

I'm not sure how this happened, but I'm showing that I have 355 PM's in my PM folder, 28 unread. Now I made sure I empty out my PM's before the change over, and, well that's beside the point because I can't see any of the PM's the system is saying I have. Redhawk

I think they are just something like empty markers for all your old PMs, sent and recieved, as you have already deleted all of them, the placeholders are empty, but still exist. *shrugs*
I had them as well, and just deleted them all.

I had some "ghost" messages in my inbox and outbox. I deleted them on the eleventh.

D Blaze is correct, there were imported PMs that you had sent to others and others had not deleted.  They are safe to delete and nothing you don't already know, but I will try to restore them to normality in your Sent folder
