For a Newbee into Joomla - this Extension is too difficult to manage.
The service/support is Okay - but my English isn´t the Best :-)
Keep it simple - and make a Manual, which is understable for a Foreinger as me, who maybe not is so technical.
Every extension has its own drawbacks, here power and outstanding features comes with little time you spent in understanding it. That's why we prepared complete documentation for you to get start with including a video tutorial. Most people find it really easy to do than it looks after playing with it for five minutes. Unfortunately you find it not the peace of cake for you. Please feel free to contact me on forum or email, I will help you setting up the complete software for you.
