"Transporter" - what a great film! Great action scenes, great car chases, a good plot and decent acting all come together! Some of the events require a bit of 'suspended disbelief', but that is to be expected of an action film. I had never heard of any of the actors before, but I think they have great futures in the biz. Definitely a good rental - well worth the money!
The idea of changing a username in windows to retain the original permissions for the new name and permission level works, to a point. As long as you are not talking about user accounts on a domain, this works great. I think there is a way to make it work for domain users as well - still experimenting.
