Register as one or more usergroups from x usergroups?

[Robert9]

In VB it was easy for me to add two radio-buttons and some code to let users choose one of two usergroups while registering. In XF i still have not watched any source-code. Before i start i would like to know if there is any add-on to have a solution for my needs.

Thank you.

Use Custom User Fields and User Group Promotions.
