Discussion vs. question threads

When you create a forum thread, the Ask option has options for both Discussions and Questions

• Discussion - The traditional discussion format with threads that only give respondents a reply field and post button.
• Question (Q&A) - This format presents the thread as a question requesting responses. It gives respondents a Reply field and a Suggest as answer check box. Suggest as answer indicates the respondent is confident that his/her answer is correct. The thread starter can verify the suggested answer or demote it back to a response.
• "I have this question too" button allows a reader can select in order to track the thread in his Profile page thread list. The number of people who select this option is shown next to the statement. Clicking the button beside the numeral will show which readers had the question.
