This new site's job is to help field common questions. It is very similar to a FAQ, but will have a lot more questions and people can submit their own questions if they cannot find one.
You will not be required to have an account to post a question, but you will be required to have an account if you want to post an answer.
I think it is important to think about and discuss how we need to change the rest of our sites and communication to work with this.
