A client of ours is interested in an event registration software, and one thing they need is support for families under one account. Basically, it would be able to keep data for multiple children and the parents, available from one login. This would be for having multiple signups to one event (both children going to a swimming event, etc.), and the system would be able to keep track of which person in the family is signed up to which events.
Not sure if this is planned, or if it would be feasible, but it's something the client requires.
I second this request. We function more as an organization for families with young children and would like the family info saved to community builder somehow.
