[DCU] How do I join the justice leauge?

Guess who's got two thumbs and lightning powers? This gal!

I have a codename, I have a costume, I've stopped a few major schemes and even got my own (somewhat small) rouges gallery! But I think it's time to step up to the big team to go futther into superheroing. So I'd like to join the Justice League. Like, i recognize I can't get in with the big seven but I assume there's a b-team or support staff something?

So...how do I go about this? Do they have an email I can submit an application to? A secretary? Or is it just a case of I stop crimes until I'm invited? If I bump into the Flash, can i ask him to put in a good word for me, or is that too gauche? Do I need a proper archnemesis? Do i have to save the world first?

I need to jump my superhero career into its next step. How do I get in to the Big Boy's club of superheroing?

Fastest way is impress Batman. His opinion carries the most weight, because he's Batman! Impressing anyone else, even Superman, would be good, but they'd  probably just put in a good word and say you are someone to watch and perhaps use for a few trial runs. But if Batman says your good enough to be League and then anyone questions him, he'll just use that Bat-Stare and they'll change their mind immediately... Because he's Batman!!!
