The technical support was great and the documentation is very good with tons of images along with explanation. At one point though, I was so frustrated that I couldn't make things work the way I envisioned so I contacted tech support. Helix got back to me very quickly and helped me work through my stumbling blocks -- which were only my errors in how I had set some of the configuration. He showed me what I needed to do and now it works like a charm! So thank you Helix for an outstanding extension and outstanding customer support!
