I don't know if I agree with that lynnJonathan, that way you end up needing to reinvent the wheel every time I think it's ok to piggyback on other peoples work, as long as they say you can (you contacting them, or they specifically said so in the readme) and as long as you are only passing off your CHANGES as your work, not the whole thing but I think it's totally acceptable to start with someone elses model as your base well, that's just my counter-2-cents =) take it for what it's worth (which is probably much less than 2 cents. unless you mean australian currency, which isn't worth much at all right now) SewerRat
