Hello:
I am pleased to see so many others in my situation - 50ish-years-old, new to guitar or just picking it up, and very happy to be getting after it.
I have found a community to be a key factor for success in anything, and I am looking forward to interacting with the group as well as pursuing a goal I have held for a long time - playing the guitar!
Good luck to all and get the heck after it!
