When I try to sign up on the bottom of the page I get a box where I need to fill in characters. What does this mean? I don't see any characters Who can help me!
You mean you cant see the Capcha ? Well Capcha's are mainly kept in order to avoid spam these boxes check that you are a human and not an automated bot. Well you cant see the characters thats strange. Try and refresh the page their might be some technical error with CJ. Mostly everyone also allows you to hear the characters so you might want to do that too.
Try with Safari or Opera. There was a similar problem with other DPr http://forums.digitalpoint.com/showthread.php?t=472589
