I apologise is the question isnt worded quite right or too simplistic in nature.
I am currently planning on building a new cms system that allows for user generated pages. similar to groups on facebook, most of the content to be provided directly by the user, i.e. news stories, pictures etc.
It is important that each "group" is hosted under its own domain, Are there any tutorials anyone can point me to , to understand how to build this type of system or guide me to the correct concept behind this.
