Actually I am. I do some support work for them. However that isn't why I came here and I will most likely never mention the software here.
I am more of SitePoint's Wayne Luke and charged with building the community on that site. In doing so, I visit a lot of different communities and work to build the best one within my abilities. My goals work with the goals of this site here. We are all in the business of building Web based communities. The software used underneath those communities doesn't really matter, it is the software in your head that will determine whether you succeed or not.
