Personally, I like to play around different forum software seeing what each one offers and how we can improve AP in general with some of these features. As of last week a new forum software XenForo was released created by former vBulletin developers. (Another forum software that exists.) Its very modern, fast, and customizable.
So I'm curious to know what everyone thinks of XF. We have installed a copy at http://avatarprime.net/xf/index.php where users can register and play around with it.
Chances are we won't convert AP to it, or any times soon. But were rather interested to know the community members thoughts on it. (And yes there is no dark AP theme on it..)
