I am a bit baffled.
re: "direct invite" - you put their e-mail in the e-mail field, Geni sends them an invite - cannot be much simpler or direct than that
re: " links that allow people to leave relatives notes on the trees for corrections or additions, etc." -- you can start a Discussion -- Public or just for Family - from any profile with notes for corrections or additions
you can send Geni-messages to all the Managers of a Profile with suggestions for additions or corrections
you can send Geni-messages to all the Descendants of a given profile with such suggestions
I do not think I am fully understanding you, so quite possibly these responses do not directly address what you are saying.
It USED TO BE the case that we could see the e-mail address of our relatives. If you look down the right-hand side of the profile of a claimed profile in your Max Family, you will see a heading: "Contact' and under it, "Email" - and that used to be non-disguised
(with the opiion in settings whether folks could see it, I believe) - when Geni changed Platforms, that was one of the changes that happened - do not think Geni has a choice in that, but if so, I would agree the actual e-mail should be shown to one's Family Group if one chooses to share it at all.
