Whats the most simple way to make a website with multiple chatrooms?

Im looking to build a site with multiple chatrooms where people can enter a room and talk about there hobbies and passions which are categorized, but I have researched and researched and can't find a solution to do this or one that is affordable without breaking the bank

The simplest way to make your website is to use wordpress cms, you only need a domain name and hosting space to store your website's files.

You can get affordable domain names, reliable web hosting packages from http://www.webstation7.com

Once you register your domain name and hosting space, just go to wordpress.org to download wordpress cms for free, upload entire cms at your hosting space and then open installer file in a browser like yourdomain.com/install.php and follow onscreen instructions to complete installation.

Now you can manage your website from yourdomain.com/wp-admin.php to add contents, images etc even manage user comments and queries too from there itself.
