Please do not be an A55 Hole!

And choose to leave a negative review anyplace due in any part or reason that you're upset about the change from being totally free after nearly 10 years to the author trying to eke out a fair exchange for the work he has put into the project. If anything, try reaching out FIRST, so that maybe your concerns can be addressed. It is really disheartening when I read reviews like this:

I mean there is such a thing as constructive criticism and then there's just trying to tear someone down. Or said another way, just being a hater. To most sensible people it should be apparent as to the problem with these reviews so I wont dig too deep. Just please don't do this. If you're unhappy... then just uninstall NiM, and move on with your unhappy self.
