Now that you are back from a long hiatus, I would recommend that you start playing ranked rounds. This is the only way to get your average down so that you can advance to higher tiers. As your tier gets higher the established clubs will have more to offer you. There might even be a mentorship program where a higher tier player helps you.
The other thing that you should do is start a friends list. any club that you do join won't offer much if you have not put other members on your friends list. hard to play multi-player games with club members when your are not friends.
