This is exactly what Software Niagara is all about.
Are you able to make it to the up coming DevTricks on Jan 12th?
If so we can make sure there are presentations on PHP frameworks, Git and Github as you mentioned you wanted to learn more about.
You are not imposing. We want more people to tell us what they are interested in learning about so that we can ensure discussions are relevant to those wishing to attend.
As @adam12 mentioned OpenHack is a great venue for getting help while you are coding, so you can ask questions specific to the project you are working on.
