What does your team use to share code?

[FRC2501]

Thanks for all the help!
I have been using GitHub for a few weeks and it has been working great! (They even gave our team bronze for free!)

Now comes the hardest part, convincing the Programming Captain that GitHub is better than flash drives, he refuses to use GitHub (maybe because he's a Senior and a Sophomore set it up and knows more than him?) and I need to convince him that GitHub is easier to use and better for organizing the 10+ programmers we now have.
