Inviting people who do not already have FamilySearch accounts
I'll be inviting a lot of cousins and 2nd cousins who don't have familysearch accounts to my group tree. I already have both their parents (living or deceased) in the group tree so there isn't really a reason for them to create a regular FS tree. My question is - when they create their account what steps will they have to take on their FS tree before they accept the group invite? Could this be streamlined to go straight to the group tree from the link I'll be sending them? Will there be a well documented process for new FS users joining a group that I can share with them as a guide?
For youth in the church with several generations of living people I can see them working only in a group tree their family has created and never needing to even see the main FS tree.
