If you’re like me and have a lot of blogs that you manage, either for yourself because you have a lot of different ideas for what you want to put out on the Web or for multiple clients if you’re a web developer with multiple clients, ManageWP is a godsend.
DISCLAIMER: While I don’t currently have an affiliate relationship with ManageWP, I hope to have one in the future (once they get their affiliate program up and running).
ManageWP makes the work of maintaining and updating multiple blogs simple. When you log in to the site (after you have set up all of your blogs), you can instantly see which sites need WordPress updates, plugin updates, theme updates and have outstanding comments and spam. Then, with a click you can either see exactly which blogs need what updates, or you can just update everything automatically.
