-There are three options (that I know of) for automatically enabling a plugin in new sites.
-
-1. Move the plugin from `wp-content/plugins/` to `wp-content/mu-plugins/` (MU = Must Use). But then it cannot be deactivated for any site.
-
-2. Click *Network Activate* instead of *Activate* to enable it for all sites. I didn't want to use this though because I didn't want to affect existing sites. Also I couldn't work out how to deactivate it for some sites (although I've read this should be possible).
-
-3. Write a plugin (in `wp-content/mu-plugins/`) with a hook that activates the plugin at creation time. This way it only affects new blogs, can be deactivated easily, and I can also set the default configuration at the same time.
