This feature has been added in our to-do list, but with a little different way the secondary Usergroups will be show in the same Column but separated with comma.

i've integrated "mycred" into my forum and added rules for secondary groups. Secondary groups cannot be synchronized automatically, but manually, so the question is: can I see the group in the users list? in order to manually modify them arrived at a certain score/points (have a total view)

thanks
