Thank you!
There are a lot of things you could do, if you desire.

Well, not through Family Gem as is now, I fear.
This app is designed as an editor of files stored locally on a single
device.
Because of this there is no need of any authentication system.
There is the "Share" option, but is actually like sending a copy of the
tree as attachment by e-mail.
So nothing as collaborative work on the same tree stored on a server online.
I'd like it could be like this, but it should be a completely different app.
