I see where we can type in Qs, but how do we answer others? Where do I click on?

Below all the Open questions you will see a blue button that says "Answer this question". Once you click on it you will get to a text box where you can type your answer and your sources (if any). Then you will have two options: blue "Preview" button or gray "Cancel" button. Press "Preview" and you'll see the answer you just wrote as it will appear to everyone. If there are any corrections, use the "Modify" button and repeat the procedure, until you're satisfied with what you wrote. Once it's ok, click the blue "Submit" button and voilà, you've provided an answer.

Click on the link that is the question. That will take you to the form where you type in your answer. You then get a preview of your answer which is a good time to proofread it and make sure that your answer is the way you want it to be. Once you are satisfied with it, then click submit.
