I think there should be a way to ask friends, not just family to join Geni. There are a lot of people out there who are not on Facebook or other social networking sites. When you click on invite you get family members or your address book. I don't want anyone having access to my address book but would like a way to enter an address myself.
You can can invite friends if you wade through the process of letting it look through your address book for family. Then all you have to do is skip inviting more family and check the people (friends) in your address book you want to invite on the next page. It defaults to ALL of them checked, so be careful before you hit send! LOL!
You can also edit your invitation template so that you would only have to type the invitation as you want it one time.
Just click on the "Invite" up by your Inbox and Account and there is a link that says "Edit invitation template."
