I thought I had done my due diligence, but now I've been informed that my "trial" of manageWP will tomorrow.
I do not need to manage multiple sites. I am using manageWP only because it has proven to be the easy way to set up a reliable backup/restore of my single, small blog. A bit of overkill, yes, but I'll have to go back and try to track down something else now.
It does bother me that there seems to be more and more premium ($) plug-in developers creeping into this repository of free plug-ins. I don't mind upgrades that provide additional features, but that fact that this is a "trial" was not noted, that I'm aware of.
