get together with a friend and be co-MLs. If you think it will be too much work, let me tell you: being an ML is as much work as you want it to be.
If you want, you can put up posters, contact media, raise funds, send out daily emails... or you can organize a kick off, a TGIO and maybe a few things in between. Whatever you're comfortable with. And trust me, people will step up to organize other meetings - you just have to get the ball rolling.
Still unsure? I promise, HQ is very supportive, as are the other MLs. Once you're in, you get helpful emails, an awesome guide and private ML forums where you can ask anything you want.
