I administer a community website — currently on dotnetnuke, which can't change right now — and I'd really like to replace my forums with something like Stack Overflow, but it has to be on my site. My users need to be able to interact with each other, and also have integrated access to the site blogs, downloads, documentation, code (open source) and bug tracker. So I have two questions:
Since Stack Overflow no longer offers commercial hosting, would they stop me from legally creating/deploying a clone?
Do such clones exist already either as a DNN module, or asp.net (mvc?) website that I can add to my site?
