I’m in the process of setting one up right now.
If you’re looking for easy, meetup.com probably is the way to go. Personally I’m leveraging the connections I made via a recent end of 10 install event I organized. My state also has a directory of LUGs that I got added to. Our first meeting is in January so we’ll see how it goes 🤞
I should add that first order of business will be deciding on a communication platform. I know mailing lists and IRC are the traditional solutions, but I’m trying to start a LUG that is more accessible to newbies who want help using Linux and don’t necessarily want to learn how to connect to IRC or learn mailing list etiquette. I’m going to push for some kind of forum software, possibly Discourse.
