We are building a website and would like to add a customized forum to our site. Below are the items we want.
* A forum that is intended for Questions and Answers and allows to search forum for keywords
* A forum that is simple to use and user friendly.
* Have the ability to register users by sending an email to address registered and activating that way. It would be nice to turn this feature on or off at our discretion.
* When a question is answered, we want that answer and subsequent answers to be sent via email to that user.
* We also want the user to be able to post replies to that answer via email
