Best contact methods for users

I've heard it mentioned a few times now that we need lists of people involved in different areas of Backdrop put onto the website, with their preferred contact method (so users know how best to contact them regarding their area of expertise/administration (be it email, Gitter, issue queue, etc.)).

I'd like to suggest a simplified way of doing this: add field(s) to user accounts on B.org where users can choose their preferred contact method(s). I imagine there'd be a main select list with different options, and then possible other fields depending what's selected (e.g. somewhere to put your username for whatever method you choose, etc.).

Then, where/when we have lists of users, we simply link their name to their profile where people can find out how to contact them.
