I had to start thinking about what software to use - do I wait for IPB 4.0.0 or come back into the arms of Xenforo. After much debate Xenforo has come out on top, so I'll be renewing my licence soon when I'm ready to start building the site.
It's been really interesting watching the progress of Xenforo and it has progressed greatly since I first used it. One of the aspects of the community that I really like is that most people are extremely helpful and the management are not condescending when someone asks, what appears to be, a trivial question.
So I look forward to a good time enjoying the software and the company of good people.
