Do you mean a webdesign program - like Net Objects fusion, a reasonably user-friendly one for instance? You can have as many pages as you want if you do it yourself. Or do you mean an online website builder that comes with a hosting package? If so and you want an easy one, I use Lycos on one of my sites - their webbuilder is very simple and as a free add-on they have simple discussion forums that are easy to set up. However I don't know how much money you want to pay, if any,and I'm sure others will suggest their preferences.
