From Josh Huffard:Can I have a check box in my jetpaks to "allow my jetfriends to add" to my package. I generally don't want anyone to add to my paks, but sometimes it is ok for friends to do so. The more specific I can target this, the better.Since sharing is now done from the jetpak page, the logical behavior I think is the 'share to a group' feature. A user will likely have one group of contacts for one thing, and another set for other things. When a user shares a jetpak, they can simply select a group, rather than one or more individual people.
