Tightknit user groups can now be viewed and managed from within the Studio! Create groups that are featured on the companion site, have automatic awards for its members, and more. Read about it here.
You can also now upload a CSV of member emails (up to 1000 at a time) to import group members in bulk. Tightknit will add each member to the group and assign the member award, if any, in the background. When the import finishes you get a clear success and failure report so you know which emails landed and which need a second look.
The bulk CSV import feature is available on the Enterprise plan.
