Organization of Programming crew in the Team

[GuyM142]

For the last year I was the only programmer in our team because of lack of manpower and some other reasons..
We have about 10 new members to the team and many of them would like to be in the programming crew, as well as some of the veteran team members.

I'd like to ask you guys how to you organize your team's programming crew?
How many members are in it?
How to you divide the work between them?
What kind of things you do in order to teach the new ones robotics programming?

I hope to get some answers to help our team's programming to get better next season
