How can I become a member of the Justice League?

Is there some sort of application I have to fill out? Tests I have to pass? I was looking into the idea of joining when I realized that I have no idea how to apply or what an application would even consist of.

When you encounter a current Justice Leaguer a few things to keep in mind.

1. They are mistaken when they attack you when you first meet. This always happens when two heroes meet for the first time in the field. Do you best to not die, and to not kill the Justice League member. Doing either will hurt your chances of future membership.

2. Always be on your best behavior. Superman can hear you swear when you stub your toe in your "secret" lair. Batman most likely has already deduced who you are. Martian Manhunter could scan your mind and learn your true intentions. Make sure to always be working towards being an exemplary hero.

3. Ask yourself, what do you bring to the table? What role could you fill if one of the big guns went down?

4. Make sure to be friendly to current Leaguers. It will take some work, but they really are somewhat of a 'who-you-know' system. Someone has to vouch for you. Very rarely will you have an unknown walk on to the team.

5. Big help, try and get into the Titans, the JSA or one of the other 'feeder' teams.

When the time is right (end of the world and/or the current JLA has disappeared into a void) you'll get a call. Make sure to answer the phone when the caller id says Watchtower.
