Yesterday we did held phpMyAdmin team meeting and we discussed several things for project future. One of discussed things was to move our repositories to github for easier collaboration and management of private repositories.
After some discussions we've decided to go for it. As I write this blog, all repositories are being pushed there and once all developers will get their access rights there, we will move completely.
But even right now, you can fork us on github, the code is already there and will be updated obsessionally until we fully move there.
