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.
