The plug-in is easy to use, flexible and has a huge variety of options. For once I'm not waiting on some functionality to be implemented for the the add-on to be useful.
I had a couple of issues getting it running, and I was able to solve one quickly with the online FAQ, and when I couldn't fix the other issue, I wrote for support and heard back within the hour. My problem was quickly resolved and everything is working great.
Thanks for the great plug-in Mike! I had no hesitation about making a donation for this one.
