Have teams for each "skill"

I currently get pinged via "jazzband/members" to review Django projects. While I would love to help, I have never used Django at all.

Proposal: Create teams for each "skill". There'd be a team for "Django", one for "Python", one for "Security"... Then everybody can join/subscribe to the teams they feel competent enough for, and people can CC those teams for more targeted calls for help.
