How can we require the selection of at least one child plan on registration.

Also, is there any way to not add users to the Registered Group ehen they complete their registration. We want to only add them to other Groups below Registered. This is causing a problem with Community Builder Tabs, some tabs are not showing because users are also on the Registered group.

I'm a bit rusty (it's been working fine for a while now), but the answer to the second question is you specify which group subscribers go into for each plan on the plan's "Access" tab. Beware this does not update group membership correctly when you renew a subscriber from the backend (in CBSubs V1.1.2).
