 * Hi guys!
 * I’m developing a plugin for WordPress and now I need to enable the plugin to 
   be used in WordPress multisites. However, I don’t want that the plugin can be
   used in the subsites, I want it enabled just in the master site.
 * Do you have any idea in how to do this?
 * Thanks!

 * Super super simple 🙂
 * In your plugin header put this:
 * `Network: True`
 * It’ll look like this:
 *     ```
       Plugin Name: Join My Multisite
       Plugin URI: http://halfelf.org/plugins/join-my-multisite/
       Description: Allow logged in users to add themselves to sites (or auto-add them to all sites). <strong>Settings are per-site, under the Users menu</strong>.
       Version: 1.8
       Author: Mika Epstein (Ipstenu)
       Author URI: http://halfelf.org/
       Network: true
       Text Domain: join-my-multisite
       ```
   
 * I would also put this check (Or something like it.) in on the top of the plugin
   file though if it can only be used on multisite. Network true only means IF it’s
   on Multisite, network only.
 *     ```
       if( !is_multisite() ) { exit( 'This plugin only functions on WordPress Multisite.' ); }
       ```

 * Hi Mika,
 * Thanks for your answer and believe, it helped me a lot. However, the plugin works
   this way:
 * If installed in a multisite installation, it need to be activated only in the
   main site and can’t show anything in the subsistes. If it’s installed in a normal
   site, it should be possible to activate too.
 * But thanks for all, I think I’m in the right way 😀

 * Finished! Thanks Mika!
