I am involved in this project, Pinta, and we are currently using GitHub for our development. We all love Git and GitHub and want to keep using it. However, now the project is getting stable and involved, and it's time we started using a more capable bug tracking system than GitHub's simple issue tracker. We also want to start doing GetText based translations. We are looking at Launchpad which has both a nice bug tracker and translation manager, but we want to keep using GitHub for development. I'm worried that these will not integrate well, and it will make development harder. Has anyone used GitHub with another bug tracking system and had any success? Any recommendations?
