Tom according to Jan van Haasteren
Tom is a systems engineer; he "does something with computers."
He has begun to set up the website in America because he came in touch with the jan van haasteren puzzels via ebay and other auction site and loved them (like many others with him).
In America, he had 10 MB at his disposal, but the site is in the course of a few months has become so extensive that his disposal 10MB proved too little.
That is the reason, that the whole has already been transferred back years ago to this website.
