Looking for some examples of folks successfully using Drupal on multiple subdomains. Is there a good way to go about using a single drupal install to manage multiple subsites like so:
All of these subsites have separate information, but some of it could be related here and there, so having it available to each subsite would be a benefit... thinking Entities here I suppose. One database and one core to update would be ideal. Any issues with setting it up? Problems with content types or entities?
