Yes it is a very good and the newest forum software that is gaining popularity very fast and is also a powerfull software for advace users and a very easy to use software for begginers.
It's got a lot of bugs actually. On AdminForums it corrupted a thread of mine (a whole tutorial!) which deleted the thread automatically. There's others but I'll stop there.
It's just bugs that occur - they will happen on any forum if something goes wrong in the database etc. It's what you get with new software - wait 1 year and it will have a lot less bugs.
Of course they will, but I'm just making the point there are bugs and this forum is not perfect compared to the others. It's worse than IPB due to it's bugs but some people think it's features are better.
