Shoutbox without sql dbase

Hi all, I was wondering if anyone has come across (or even using) a shoutbox that doesnt require an sql dbase. While it isnt hard to access one id prefer to write everything to a file (wanting to learn how to write, append etc files) I tried one but for some reason the script processing turned into some random java script about symwindow openning etc -has anyone heard of this or know what it means? Thanks all Greg
