I use Tribalpages to build my tree, not for connecting to others. My privacy is a "custom" setting.
There is the "connections" page[?] that shows other Tribalpages trees that have the same names that you can contact.
If you want a site that people can connect with you then Tribalpages is not the one to choose, maybe Ancestry would be better suited?
Although, if I enter my site name into google it throws up my tree near the top.
