automatically add all attendees to networking

it would be better if attendees are automatically added to Networking and then they have the option to opt-out. The Admin should be able to decide if they want everyone to automatically be added to Networking (with attendees having the ability to opt-out as I noted above) or to make the networking opt-in (as it is currently configured. In planning events, I find this extra step a lot to ask for attendees, when most would be fine with networking, particularly b/c they like the option to see who is in attendance.
