I received the following PM from member bilalbz:
"I have been submit a new post in the Cell Phones forum, but I am unable to do so. As soon as I submit, it shows me a blank page. I have tried two different machines, on two different networks with Internet Explored 6 and 7. I've tried submitting post that includes a hyperlink and without any links as well. Same result. Would really appreciate if you could help me figure out whats wrong.

Given he can post to other forums but not Cell Phones, and it happened on separate machines, it sounds like a forum issue to me, one which has been mentioned before.
