Thanks Matthew 
Well it uses 1 less column per table to achieve the same goal so that’s a win. Ya collection of real emails is mission critical for a lot of us.
Nothing else really comes to mind that you can’t already do with anonymous + roles… because essentially that’s exactly what I’m doing
It seems your method solves all but the notifications issue, but it’s limited to how many private users your plan allows and how many you need. Haha 1 less column. I have users enter email again during onboarding to get real, but doing it that way I’m counting on them to put a real email and without typos. And the user is probably confused why they’re being asked again. I really want glide to switch to user IDs… oh the things out of our control…
Good stuff, thanks for the link. This will be amazing to use.
