BuddyPress.org

Hi guys,
I need a solution to add people that signed up via gravity forms “User Registration Add-On” to a specific buddypress group.

Group-o-Matic Plugin looks like a very good solution:
https://wefoster.co/buddypress-group-o-matic-adding-members-to-groups-based-on-profile-fields/
https://wordpress.org/plugins/buddypress-groupomatic/

But it is very outdated. Or does it still run on an up-to-date Buddypress and WordPress installation?

Do you know an alternative? Or another solution for my problem?

Thankyou for your support!
Cheers,
Matt
