javascript form problem

go to http://www.clanhonor.com/chat and register and login to look, it only taes a second.
my problem is, when you press enter to send a message, it doesn't use the selected text color and it doesn't clear the box after submitting. the say has an onclick() handler attached, and the form has an onsubmit() handler.

i can't find any useful handler to use for the text field, and i cant get it to trigger the onsubmit handler. halp

the onsubmit handler only works in the <form> tag. make sure your putting it in there,

when the page refreshes you might want to make it drop down to the bottom of the page
