Also included in the script is sqlite3 to take note of all invited users, regardless of whether they accept or not, to ensure that users aren't sent more than one invite.\n\nWhy automate the invite process? Because I was previously opening two tabs, 1: the invite page here 2: whatever member list I had, and manually entering each and every name. It's a tedious process that takes a long time and there is no built-in function for inviting a group.\n\nIf you received more than one invite, I apologize.
