One marvelously clever thing that was suggested at the "Why is SF so White?" panel, as a means of encouraging more non-white writers into the industry, was a mentoring program. (Liz Scheier, from the audience, also mentioned that she doesn't see nearly enough submissions with non-white protagonists or main characters, and would love to see more.)

The idea being that would-be writers of color could be paired with volunteer authors who would help mentor them.

I am not the person to administrate this. I know this about myself. But I thought it was a good enough idea to be worth sailing out into the zeitgeist.
