I'm normally not the guy who writes reviews but this time I have to.
For the component itself I just can say "Amazing!". It's easy to install, easy to manage, looks great, works out of the box what else to say. I've you're looking for a component where users can discuss under each other, this is is the component you need. This may sound as I am an employee of stackideas, but I'm not.
The support is thus even better as the component itself. After Installation of a new plugin (I have to mention that it was in beta state) I had some problems. The guys helped me out in no time and fixed all issues directly on my page... No action needed from my side.
Absolutely every penny worth!
