We'd love for alums to enter their social media handles, for us specifically their linkedin address, while stepping through the sign up flow, and it should automatically populate the LinkedIn address field in their profiles. For that matter, why not make the signup flow admin section the most flexible it can be and allow us to add or drop various fields such as social handles, but also others. Not sure why the strategy/reasoning was behind allowing some with the new rollout but not others. This is frequently our one opportunity to capture as much alum data as we can get!
