Today, I'm following the lead set out by Solspace and Exp:resso (among others) and releasing a bunch of goodies onto GitHub. I love the idea of making things easier and fun for users and developers and GitHub is a great place to do that.
First, all mithra62 add-ons that have language packs now have those language packs available on GitHub. This includes Backup Pro, Backup Pro(ish), CT Admin, Export It, Automat:ee, Securit:ee, and Flag Master. If you have any translations for those add-ons please do a pull request to make them available to the community. Oh, and all translators will receive a free license for the add-on they've translated once it's been officially merged with the repository so get on that multilingual EE people.
Next, with the exception of Backup Pro(ish), I've put the "free" add-ons onto GitHub. Right now, this includes EE Syntax and Meetup though any new free add-ons will be on GitHub as well. The only exception will be add-ons, like Backup Pro(ish), that are loss leaders and released to build awareness in another product. It just doesn't make sense to release add-ons like those on GitHub.
Hit me up if you have any questions or concerns.
