Hello, As I understand it, the git conversion will require an email address for any commiter in our subversion repository. The way we fill the email address currently is through the USERINFO repository available with subversion at: http://svn.wikimedia.org/svnroot/mediawiki/USERINFO Each file is named according to a svn author and filled with various fields. The email address can be filled under the field "email:" and can be obfuscated. Example for author "hashar": name: Ashar Voultoiz email: hashar at free dot fr url: http://fr.wikipedia.org/wiki/User:Hashar irc: hashar languages spoken: French, English father: yes I have just imported in subversion the list of authors from the code review extension deployed at www.mediawiki.org. It would be great to fill in the email: fields for each of the author that are missing it. It will ease the git migration :-) A shell one liner will get you an up-to-date list of author files which are missing the "email:" field: egrep -c ^email: * | egrep -v '1$' | cut -d\: -f1 | sort In case an author is an alias, you can add an "alias:" field to the new user name. For example gwicke used to commit with the name gabrielwicke hence is "gwicke" author file has the special field: aliases: gabrielwicke The output for the above oneline is below. Please help populating email address :-) abernala abigor aboostani adam adammck adhair ajvol algorithmix angelab axelboldt b_stancescu bachsau balasyum bartek beckr bhagya bradneuberg brezelben diana dschwen emiller erwin85 evanprodromou fabianh flominator fptc fvassard gmaxwell greenreaper gri6507 gslater harddisk hhappel jonwilliford lcrocker mbrad misza13 mulligen nojhan robh root rscheiber sanyamgoyal shaihulud swiftlytilting tgries tor warddr yaauie -- Ashar Voultoiz
