Hi Perposan and welcome to the forum
Guess what - we've got no idea either, but you might find the terms 'database', 'PHP' and 'HTML' useful. If you don't fancy that, try a CMS, e.g. PHPNuke or similar.
One word of warning: don't do what 123 Greetings and Passion Up have done and include lots of pop-ups and pop-unders - they're very annoying.
All the best
Norm
