Add user to a group ?

[Sashkan]

Hi !

I'm trying to add mailchimp to my app. So far, I managed to subscribe users to my list, but I'm stuck.

My list is split into 2 groups : admins and Users.

Whenever a user register, he should be added to the "users" group. same thing goes for admins.

The thing is, I cannot find anything group-related in this bundle. is there a way to do so ? Subscribe the user and immediately add him to a group ?

Thank you
