Yes, I've used the latest version, I think 2.07 or something.
It's an extremely impressive application with more features than I care to examine. Becoming an expert at it would take half a year their is so much built into it. For the price they sell it for you can't go wrong.
I also have a problem with it's speed. You must enable zlib and all the caching possible to get a faster loading site, otherwise it's simply too slow. And that is when I had it hosted on a cloud server AND also a VPS, both are slow, it's the code that must be cached.
