http://qhub.com/ – Qhub is a simple way to create a Q&A website. While other Q&A websites are great for information sharing and communities, Qhub offers a more targeted community managed by the people that are interested in that particular subject area.
Each group is set up and started by an owner. Friends, colleagues, club members and more are invited to join and the questions can begin. Qhub offers the ability to customize each site. There is full management of your site, its members and content. It also offers the ability to use your own domain name.
If someone asking you a question and you have the answer, why not open up that knowledge to the web community for their and your benefit?
