You are SOOOO True. ;(

and I am a little scared that I might do something that corrupts the origin repo! Heeeelp!

No. You can't do that. Only Mark can write. You can only work at your own copy.

I am using command line Git and Windows Github at the moment but I am about to install Eclipse so I shall hopefully use that for Git instead as it is all nicely integrated. Does anyone else use Eclipse?

No, sorry.
