I'm not sure what you need. PMSE doesn't really use chat as often as other sites do, so you may not get a lot of responses here as opposed to asking an on-topic question on the main site or on our meta.

A lot of the technical folks on PMSE use Git, or are at least familiar with it, and some of us are also Git ninjas when we're not out fighting crime in our superhero costumes. If your question is on topic for project management, go ahead and ask it on the main site. Otherwise, let use know what you need and we'll see if we can at least point you in the right direction.
