Jetpack is a plugin we’ve been running on a number of different blogs for some time now. It adds some additional functionality usually only reserved for bloggers using the WordPress.com service. Some of you may have it activated on your site already. We’ve developed a way to give everyone access to some of the modules in Jetpack. Staff will be able to extend that functionality by going into Settings/General and toggling on the “Enable WordPress.com Jetpack functionality? ” which will open up the option to sign in with a WordPress.com username and password (separate from your Commons login) and add more modules.
What this does is allows us to use Jetpack with students who otherwise wouldn’t be able to sign up for a WordPress.com username because of age restrictions, and allows staff to take advantage of the service on their blog if they want to add additional items.
If you were previously signed in and are now seeing an Development Mode notice in the Jetpack settings, simply go into Settings/General and turn your JetPack back on.
