I personally don't know Git, and while I'm sure I'll be learning at some point, I'm always nervous about learning a VCS on something I care about, as mistakes can go quite wrong. If I can lend you (or someone else) a hand don't hesitate to contact me. (I'm not a git guru though..) With git you can't get too much wrong because it's very cheap to create additional pointerns / branches.. So if you clone a branch before taking any action you can always reset the messed up branch to the "backup" by git reset --{soft or hard} backupbranchname Or you could write a two line sh script writing all hashes to a temp file etc.. If you just start gitk it will keep all hashes in memory.. so you can recover from those as well (unless using the update menu item or running the garbage collector)
