New Recruit Problem signing In

I invited a friend but he is having problems with his log in - any suggestions?

Here is his email to me...

I created a login ID for the site you suggested. But even when I am logged it,it says "You must be logged it to submit a solution." I also cannot post to theforum to complain about it. Can you post something? Thanks.

I have all of them, including today's, finished.

I just can't submit them because "You have to be logged in to submit a

message" even when I am logged in.
