New member signup?

Got a buddy trying to get on board here.
Keeps getting the below message.
Any input for him?

Has he tried listening to the letters or request a new capcha? Sometimes I have to do that in order to make it easier on my aging eyes 

I would also try switching browsers next. Good luck.

Also, make sure he is doing the "CDEF" correctly. The forward and backward part tripped me up at first!
