Damn you beat me to it.  

Man, our reputations must be LOW!

Hello,

There was actually an effort to get a dotnetnuke focussed site on stackexchange (Mitchell Sellers started it as far as I remember). Whilst we made it through the first couple fo steps, it did not gain enough interest to become final and was deleted. This suggested there were not enough dotnetnuke users with the interest to use it (most people automatically come to dotnetnuke.com)

However, lots of us (Core team and Corp staff) are fans of the approach, so we've created a module which does a subset of what stackexchange is. The biggest value here is that we can integrate to the vast amount of knowledge we already have e.g. at present AFAIK when you ask a question it will search to see if a similar question has been asked. As this is running on dotnetnuke.com, this opens the possibility of us extending that to check the forums/wiki/video library etc for related information. Theres also lots of other things we can do as we have access to the data - one of which will be improvements to community reputation (including the ability to grant more privileges the more you participate)

Finally, the module itself has been released as an open-source module, which means any user can install this onto their website and not have to try (and likely fail) get their subject passed as a stackexchange site.

Thanks.
