Yes, I do pop in in here in my spare time.
I am also on the Koozali board, help write wiki pages, fix bugs, write code (your server is probably using some of my freely contributed code right now so you better hope it is good) and generally help as much as I can. As I have for 20 or so years.
Last time I looked the mc plugin did work.
You are welcome to continue looking by yourself, and I'll go see if I can go help get SME v10 finished so you have something to upgrade to.
Do feel free to come and help.
