 Let's say my domain is 'intridea.com'. Here are some examples of the use of the :subdomain
 option:
 
-url_for(:controller => "my_controller", 
-        :action => "my_action", 
-        :subdomain => "awesome") # => http://awesome.intridea.com/my_controller/my_action

+          :action => "my_action", 
+          :subdomain => "awesome") # => http://awesome.intridea.com/my_controller/my_action
 
 Now let's say I'm at http://awesome.intridea.com/ and I want back to the root.
 Specifying "false" will remove any current subdomain:
 
-users_url(:subdomain => false)  # => http://intridea.com/users
+  users_url(:subdomain => false)  # => http://intridea.com/users
 
 Note that this plugin does not honor the :only_path notion of routing when doing
 so would go against the intent of the command. For example, if I were at http://intridea.com
 again:
 
-users_path(:subdomain => "fun") # => http://fun.intridea.com/users
-users_path(:subdomain => false) # => /users
+  users_path(:subdomain => "fun") # => http://fun.intridea.com/users
+  users_path(:subdomain => false) # => /users

 same subdomain when you meant to change it.

 always want your links going to 'www.yourdomain.com' instead of 'yourdomain.com',
 you can set the preferred mirror like so:
