Drivers

I have an applicant waiting to join my clan, and the clan is full at the moment, but how do I remove a low scoring player in favour of bringing in the new applicant? I have tried the remove button and it does not seem to work! I have asked the low scoring player to move to another clan and he is happy to do. HOW DOES HE DO IT?
This is a great game buy the way....Congratulations

Fixed, thanks !

New Thread I just fired one of my drivers (I didn't like him) my new driver must be working for someone else as his car has a different aero package from mine
