[jwmw1023]

ok i posted this somewhere else for a specific issue, but just to see what kind of knowledge i can learn, if you want, fix this script or make it better. i wll take your changes and integrate them into a pc toolkit im building and then put it on the web as source, but this is mainly to learn stuff the best way that i learn. this is the code, post changes back here or leave a note for a email address to put them in::::::
