I recently discovered WP Remote's free site management service. With over a dozen WP sites to manage, several times a week, one or more plugins would need updating on one or more sites. I was getting sick of logging in and making these routine updates. With WP Remote, I can do it all from one dashboard. It's easy to set up and intuitive to use. You can remotely check and update WordPress core and themes, too. No, I don't work for them - I'm just a happy user!
