The Maker Plan is awesome for a community since Unlimited users can join as part of the plan.
The limitation is that they need to use their personal email ID. (gmail, yahoo etc.)
The problem I am facing is that I am creating a community for Business Owners and they prefer to use their business emails IDs by default.
Two people had to create a personal email ID just so they could join the app.
The solution is (for those who need it): An add on for the Maker Plan where email IDs of users can be personal or business email IDs.
