This probably needed to go in tortoisegit-users but I can't find it on Google groups. Feel free to move it if that helps.
Basically, I have some git repos hosted at github. Up to now, I've been able to push to the repos via a user name and password - but github is apparently moving to SSH access only. I have my SSH key (.pub file?) as well as a Putty key (.ppk file) and I've registered the .pub file with github.
IIUC I now need to add the Putty key to my local TortoiseGit project (which I've done under Settings->Git->Remote. But when I try to push that repo, I'm still getting asked for a user name and password. Is that github's fault - or something I need to change in my TortoiseGit settings?
