Fortran, if the member gets the moderator colour in the who is online box, then you must have made him a moderator.
Go through all the steps again, and see where you went wrong.
Go to User Admin >> Management
Type in the members name, klick Look up user
The member's Profile page comes up.
Go down to Special admin-only fields >> Rank Title
On the drop down menu next to Rank Title, you can see what rank you have assigned to the member.
By changing that menu, you can give the member a rank, and then click Submit, at the bottom of the page.
