I would like to know how can I make to allow my users choose their RS group upon registration…thank You for your help

I'll make a note of your interest in that feature, but I'm not prepared to add it to Role Scoper at this time. I am available for hire if you want to commission a separate plugin to meet that goal.

I'm generally available at a rate of $50/hour. Venturing a rough guess, the functionality you ask for may take me 3 or 4 hours. If you want a more definite estimate, let me know so I can investigate the related code more carefully.
