I downloaded this component and bought the plugin for my Sobi2 directory component. The goal was to have a business directory with SEF URLs. I did not desire or need the rest of my site to be SEF. I ran into difficulty trying to configure it but to be fair, this component has a lot going on. It's easy to not do it right if you are uninitiated. I emailed the creator and he asked me to pay for one hour of support. I am sure I took up more than an hour of his time but he stuck with me until the component was working. Any difficulty that I had was my own lack of knowlege. Now installed right, it works as advertised and I'm thrilled at the job it does.
