I understand that, but in this case the server admin and myself were the same people, on my home server, so there wasn't anything leaking anywhere really.

That being said, this was about a year ago. Invite links that you can send manually by email and people can join the team would be more than sufficient, I don't need the system to send the email for me, I just need an invite link.

The problem was the reverse, I needed each user to send me an ID (I think it was an Id) so that they could be invited.
