Progress...
I actually found an easy to use, yet powerful CMS (Content Management System) for the WBTA website.
It's called Mambo (
www.mamboserver.com ). It's Open Source, so free, and there's a reasonable number of add-ons for it, including templates.
The main advantage I found is that everything is managed via the admin menu, which is a web interface, from which one can upload ZIP files of add-ons (components or modules).
The articles/stories take some getting used to, as they have to be categorized, as well as sectionned, but there's an option to keep items posted or unposted, public or registered or admin only.
Nice, simple, and powerful: exactly what I've been looking for!
(begin shameless plug) I put a game module somewhere on the site:
