Very sophisticated support system. Cleanly coded and powerful. A must have for any community. Excellent support by the author as well who is always available to respond to any query. Well done Nixfifty.
For the price you pay for this, you're getting a really solid well-integrated add-on that offers a lot of functionality I've found lacking in addon ticket systems in the past. The fact that it also comes with a simple knowledgebase is just another perk that makes it worth buying.
This may not take the place of a full time support desk solution like Kayako or others, but it's damn near close, and the integration makes it better for communities in my opinion.
Once again Nixfifty comes through with an amazing, much needed, add-on for any community. He creates excellent products and takes development updates directly from his consumers (which means a lot to me), he's open to sensible custom development and always quick when it comes to supporting his add-ons and providing support you can *understand* - because trust me there's some out there that don't take the time to help you with that. Just A+ all the way!
