Ok, I'll install git on workstation, where I'll be running the bash / gui from but I'll create the repo on the server (for backup purposes) - so won't need to install git there I'm assuming?

super! I'm sorry distributed SCM was new to me last time I used SCM was 10yrs ago - Visual Sourcesafe, PVCS (grrr), clearcase (not bad)

that's great, it will allow us to capture the flow of work in our project so far, and amend if some other version turns up ! Your answers are enough for me to proceed and give git a go.

thanks, your overview here has really helped
