Hello everyone, I'm just wondering why are Q&A wikis different from database wikis. I mean like, when you create a wiki automatically it would be just an ordinary one, but how do they confirm/verify that the wiki they're going to create is a Q&A wiki? And how do they get that "Welcome to (example) Answers. What would you like to know?" Then below that is a box where you enter your question then automatically it will be there.

Can someone explain to me? I'm planning to create a Q&A wiki about a certain topic, that's why I want to know.
