Forum OpenACS Q&A: Response to Multiple sites, one AOLServer, and one database?

Reuven, check out GrandEx. It was built by aD, and makes good use of subsites.

Subsites might turn out to be the killer application for openACS. Being able to provide a complete web presence for a parent organisation while allowing each subsidiary to customise its own look and feel is not as unique a requirement as one might think.

As PhilG might put it, it becomes a lot easier to build purposeful communities around particular subsidiary/product/brand/department/region .....

With subsites, portals, groups and host-node-mapping (dotLRN anyone?), one can build some really powerful websites!
