It is nice to finally have a Joomla integrated raid planner that is kept up to date (I'm running Joomla 1.7).
The CSS is easy enough to change too if you have any template issues (I have a dark template and had to modify a couple of colours).
The developers provide excellent support too. I had a few issues which I reported on their website and I had a response within an hour with instructions on how to fix it. They also seem happy to add/change features to meet the needs of their users. I've not seen support like this very often even from paid extensions!
The only negative comment I could make is that the website could be a bit more user friendly. It is not natively English which makes it a bit confusing at times (If you need to post in the forums the registration process is not in English).
I still rate this product 5 stars as the extension is great and the support is second to none and I was still able to work out how to get support even with the website in its current state.
Thx for the positive feedback.
I've changed the support site language to english.
