i would just like to thank mike, ray, joe, steph, tommy, bob, karren and
matt (i think that's all) for their welcomes and their information. i
haven't yet had the chance to properly read all your responses but will be
printing them off to look over more thoroughly, and no doubt will have lots
more questions then! :-) i just wanted to thank you all for responding so
quickly and helpfully. so THANKS! :-)
