And. here is the text of the post and a description of the problem...
Apologies in advance for posting this in what is likely the wrong place, but I'm really struggling with my account and the GeekU area is the only place I can post. Also, and more importantly, the the reason I'm posting is because I can't PM either.
This is the error that I'm getting.
[#10223] You are not allowed to use the private messaging system.
I used to be able to PM and now I can't nor can I read my old PM's. The only thing I've done to my account recently is change the email address associated with this account.
