I am thinking about setting up a wp site with 3 blogs on their own subdomains and I was wondering if i could install only one version of wp to handle the 3 blogs.
Basically i'll have http://www.example.com as the domain and blog1.example.com; blog2.example.com; blog3.example.com. On the root page I would like to be able to display info from all three blogs and all the login info. I know i can install wp on each subdomain and then try to hack it to have common login and be able to display latest posts.
Any ideas on how to structure this would be really appreciated!
