WARNING!!!!! The demonstration version of this script allows anyone to chat (otherwise, it wouldn't be much of a demo, now would it?). However, some immature and otherwise silly people like to post obscene comments or other such stupid things. Don't ask me why -- maybe they think they're funny. :-) At any rate, if this sort of thing offends you, please go back to the SFEChat page, and just download the script to set it up on your own site to test it. If you feel you can deal with the potential of seeing bad language and offensive comments, go on to the Demo.
