How does drupalgardens.com creates a new website?
- It creates a separate directory for Drupal, containing all core files(modules, themes, includes, ...)
- It shares the themes, modules and core files, and just creates a sub-site in drupalgardens.com
The second one is more reasonable, But When I read the source HTML I saw the following line:
<link type="text/css" rel="stylesheet" href="http://[mysitename].drupalgardens.com/modules/acquia/gardens_client/gardens_alert.css?lva62a" media="all" />
That, in my opinion, says that my website is outside of drupalgardens and has a separate directory instead of being a sub-site in drupalgardens.com
