I'd like to make a question and answers site, but I'd prefer not to do it in a forum environment. I have used one recently that I really like, and I'm attaching a .jpg of how the questions list looks. The site can be clean and very basic, as I'd like to keep the cost as low as humanly possible.
Basically, I would need the following functionality:
-Post a question
-Reply to a question
-Reply to a reply
-User profile page, w/picture, showing answers and questions they've posted
-E-mail notification when a new response is posted, with a link that goes directly to Q/A thread in e-mail notification
-An area for Google AdSense ads and 1 banner ad
-A home page with links to multiple cities and ability to launch duplicate sites myself using subdomains ( i.e. [url removed, login to view], [url removed, login to view])
-ability to keep favorites
-E-mail a question/answer thread to a friend via website
When posting or answering a question, users would enter first name, e-mail address (which doesn't appear on the website, and they answer the question "I live in New York/I am visiting New York" and an opt-in question about receiving emails from us.
