I'm trying to help a friend that is setting up multiple XOOPS sites at the same time. He's starting a portal where users can access different clan websites for different online games. He is trying to do this by starting with a main starting page at his root domain (www.ralogames.com) which will contain links to different clan sites which he's got running on different subdomains (example: wow.ralogames.com). On each subdomain, he's installing a separate instance of Xoops. One thing the sites have in common is that they are all sharing the same database, just using different prefixes for the database table names.

Is there a way to have users register on the main site and have their user information available for each of the subdomain sites to use?

I'm trying one more time to get an answer to my question. Anybody have an idea if this is possible? Couldn't I point one website to the user records of another?

There is a multi-site hack somewhere..just do a search for multisite and you should be able to get information.
