Ensuring high quality sources where needed, especially science/academic topics (narrow focus)

Actualy, this is smth I have never thought about but it seems like a very good idea - I mean, not necessarily making people to go through the workshops but generally (a) stating that quality contribution typically require certain skills, which are obvious to people knowing what the academic research is but may be less obvious to others; (b) providing opportunities to learn this culture - via workshops or other means; may be even live workshops organized by chapters.
