From their Meetup Page:

The GA 400 Linux Group has been started to allow the casual to advanced Linux users to get together and share ideas, knowledge, and face-time with other Linux users.  We're focused on helping beginning and returning Linux users learn the basics by establishing a solid foundation.  We'll discuss distributions, file systems and storage, installation, databases, networking, and more!

Looks like they have informal weekly meetups at a pizza place, and more formal monthly sessions.
