Add a key contact

A Key Contact for a batch / class is somebody who will be able to help reach out to his/her batchmates and help build the database for that class / batch. Do not worry about whether they will be willing or whether they will have the time to do this. We will reach out to them and call and confirm their willingness and ability to be a Key Contact for their class / batch and contribute towards this initiative.
We will need at least one of the following contact information to be able to reach out tothe Key Contact. It would be helpful if you can please collect any/all of these pieces of information about the Key Contact if you have a way for doing that. We will still be able to find out contact information about the person if we know that such a person would be a potential Key Contact for the class / batch.
