Hi Allen,

While you can only choose one "Association" currently, you can set up as many "Linked Groups" as you want. You will need to become a member of the group that you want to link to on Weplay, and then click the "Link my Group" button on that group's profile. Repeat as necessary. By default your linked groups will be shown on your group's profile and public page.

Hope that helps!
Luke at Weplay
