I am reviewing the free version of InfiniteWP which includes
Update all your WordPress sites, plugin and themes in a single-click.
If you manage more than a few WordPress sites, this plugin is a gift from the software Gods.
The premium version can do a lot more, and I want it! But until then, I’ve discussed my workflow using the free version in this video, and also compare it to iThemes Synch (also free version).
