Install Stendhal

Get a domain name

You can get one for free at http://www.dyndns.com/

You already have MySQL to run Marauroa.

If you want a stendhal website working, then configure Apache to attend your domain name.

If you want a stendhal website, copy to your Apache htdocs folder. Else ignore.

Edit settings.xml

Tell users to use your domain name to log in Stendhal instead of stendhal.game-host.org

If you used a port other than the default port 32160 tell them that too.

You can also release a modified client.
