Ok guys, here is the issue: I can't see any private message in the pixeljoint gallery site, but I get the email that I got a private message in my email inbox.

For example, today my P.M inbox said "no private message found", and because  those coincidences in life, I checked my email afterwards, and I saw that I got a private message earlier than the time I entered pixeljoint. I go to pixeljoint again and no private message  found. I could reply to the p.m through the link in the email, but I found this rather odd and I thought I should report it.

Yup, I checked the private messages here in the forums and nothing either.
