Night's correct on chapter lengths.
It kinda depends on where you're posting this, too. Blog readers seem to have fewer expectations on chapter length. People in the Pit may find anything less than 2000 or 3000 words short for a chapter, but if it's good they're less likely to notice and they can go stuff it anyways.
Opinions and philosophy differ on what should constitute a chapter and you're the only one who can decide what's right for a particular story. Mine usually run anywhere from 1500 to 7000. I try to have one significant event happen a chapter, and I try to enter each one late and end each as early as possible.
There are no set rules on chapter length, really, though many people will spew their arbitrary rules at you. Screw 'em.
Many are just upset that so many children writers post short little 500 word snippets as "chapters" in the Pit and then they want to outlaw it forever so their eyes are never offended again.
