you should give her author credit and say you modified it, along with her web page too perhaps?... and a way to find you (e-mail), so if she learn that you modified it, youll be contacted. err.. i think. it depends also on the ammount of code done by her. is this a hack for ubb?
edit: if its a free script, there should be no problem. put her e-mail along with the code too, even if its not working.
