Is it possible to invite family to my site and have them able to see only one of my family trees? I would like to invite my husbands family to only see their side and invite my family to see my side. Neither side is interested in seeing pictures or getting email reminders from the other side of the family. I hope this makes sense to you :)
It's currently not possible to invite someone to only one tree on the same site.
It is possible to invite one member to one site, but not to another site owned by the same webmaster.
I can see that you have 2 sites. If you'll put one tree of one side of the family in one site, and the other tree of the other side of the family, in another one, it should solve the problem.
I'll forward this suggestion (Making it possible to "block" one tree in the site for certain members) to our development team.
