I too am looking for something like this for my gaming community, we have over 9 different divisions(games) we play and would like to have the main domain and then sub-domains to each game like gw2.domain.com and when people go to gw2 sub-domain it has its own GW2 theme and has its own forums.
However I want things like News and Announcement forums connected between the two. Then the GW2 members will have their own private forums on the sub-domain. If that were possible it would be amazing.
All I get is this error when accessing setting in admin ACP
The website encountered an error while retrieving http://www.swgaming.com/admin/index.php?adsess=d235312dca65b87bce55e44b66ea6087&app=iStream. It may be down for maintenance or configured incorrectly.
Here are some suggestions:
Reload this webpage later.
