That was quick. I’m now able to turn on Google+ on my Google App domain. If your Google Apps then try logging into your “Manage this domain” link, select “Organization & Users”, then Services. If the option is available you will be able to scroll down, find it, and turn it on. It’s that simple.
There caveats is that this looks like a work in progress. I’m not able to get Google+ working via my Android phone or either my wife’s iPhone or iPad. But the web page works fine and I’m able to login using my Google Apps account.
Now does anyone know how to get all their FaceBook friends to migrate to Google Plus? That’ll be a fun social engieering effort.
