 * Hello All,
 * I just installed 3.1.1 with Multisite support (subdomain) and applied the WordPress
   MU Domain Mapping plugin.
 * In the Network Admin Panel i can configure “Sites”
    In the “Settings” submenu
   of the Netword Admin i see “Domains”.
 * In each one of this admin options i can “Add New”.
 * I really don’t understand the terms and their use. What is a site? what is a 
   domain? What is “Site ID” that is assigned to each domain i add?
 * My goal is to have a single WP installation to be used with 3-5 different domains
   and have blogs on several subdomains of each domain.
 * [http://www.domain1.com](http://www.domain1.com)
    david.domain1.com daniel.domain1.
   com stacy.domain1.com [http://www.domain2.com](http://www.domain2.com) james.
   domain2.com lisa.domain2.com rollo.domain3.com dido.domain3.com etc etc….
 * Is that possible? How do i add a domain, add a subdomain to it and assign a blog
   on this subdomain?
 * Current situation:
    all domains are resolving to my IP, apache (on a dedicated
   machine) answers all requests, all domains use wildcard subdomains so apache 
   answers all requests. I have installed everything (WP+plugin) using domain1.com
   so it is considered as my “site URL”.
 * I know i posted many questions here but after installing everuthing and reading
   all the available documentation i still can run my network as described above.
 * Many Thanks to all helpers!

 * Sites are the subdomain sites you enabled when you created a network. You have
   to make one there before you can map a domain to it – under the Domains tab.
 * It;s a lot easier to understand how multisite works if you examine it before 
   adding plugins like domain mapping. 😉

 * If you want your extra domain to have child sites, then you do not want to use
   domain mapping. You need one of the multi network plugins like this:
 * [http://wordpress.org/extend/plugins/wp-multi-network/](http://wordpress.org/extend/plugins/wp-multi-network/)
 * It works slightly differently – you have to use the menu it gives you to create
   the second network, and it will map the domain at the same time. then those domains
   can have child sites (subdomains).
