Okay.... Check this out:
It's the "Liberty Meadows" FAQ. In addition to being hilarious, it has tips
on how to send a submission to syndicate editors.

Something to keep in mind: Most, if not all, will say "no" the first time.
It's heartbreaking, but you have to keep chugging (at your work, not
at a beer!) and keep submitting. I got turned down zillions of times
before I finally sold a Kirby (vacuum cleaners, not pink puffballs). If

teaching job right now!
Dare to believe! Fight! Ganbare! Hoo-yah! Use the Force! Victory or
