I never like to spend money on plugins since just about any thing you want to do you can get for free. I needed a plugin that did cross refrence linking. I have thousands of articles that needed to be cross refrenced that are in different sections. This was the only plugin that did want I wanted. I had to contact support because I was not following directions properly. Support pointed out what I was doing wrong and even fixed my problem for me.
I never take the time to write reviews about anything really. But the makers of this plugin deserve credit where credit is due. Great plugin in and great customer support.
