Add all contacts
Great site with only a few minor improvements to be great like Phanfare where I come from.
Add box to add all contacts in address book when sharing by email on website (and in iOS app later).
Right now, you have to click on one contact at a time. That option should have been there from the start like in Phanfare and should be easy for your team to implement.
I could use a batch add contact feature. otherwise having contacts on my site is worthless. Who is going to add every contact?
