I was going to write my own version of George as I have a background in IT myself, I downloaded a copy for a quick look and it seems like a good piece of software. I think it's an old Access database by the look of it but there's nothing wrong with that as far as I can see.
As with most things, when someone writes something for their own use it's normally better and George seems to have been done by someone that knows his stuff.
