I've just tried this (commit c1fa07a). Recent changes shows:

Note that the user for the commit is 'jon', and the link points at cgi to create users/jon. I was wondering if that is configurable for users pushing via git. It would be nice perhaps to specify it in some way, perhaps via a git-config setting (user.name?). I'm not too familiar with exactly what the changeset contains. -- Jon

All ikiwiki can do it look at who git has recorded as the author of the change (and it looks at the username part of the email address). You can set user.email in .git/config. --Joey

Ah, excellent. In which case this should DTRT... -- Jon
