I am trying to make an invite app by using the free program. In this app, a user can create an event with basic information (location, event name, address, etc). I am trying to figure out how the user can create an invite list and sends an invite to the specified email address (invite by URL link would also be nice). Only the persons specified in that list must be able to enter the form with the event.
I hope someone can help me with this. Also, if additional information is required to understand my problem, please let me know.
