I really do not understand why people use GitHub over Gitlab AT ALL.
GitLab consistently brings out AMAZING features at least 1x/month. Their company is ethical (donates regularly to amazing coding groups like BlackGirlsCode, DjangoGirls, PythonLadies, etc.).
Just look for yourself: https://about.gitlab.com/features/
@mawr I forgot to mention in my original toot that GitLab itself is also OPEN SOURCE! They practice what they preach!!
Glad to open you up to GL -- I really, really love it. The continuous integration is MILES ahead of everyone else, too!!
