When you have a goal on your list that you’d like advice about, you will have a green link at the bottom of the page that says “Ask for advice on meeting this goal”. Clicking this link gives you a text box that you can write your question in. Click the Ask! button and it not only adds it as an entry to the goal, but also emails it to anyone who has completed the goal and indicated that they are willing to help others. That’s how I knew your question was here, because I’d marked this goal as complete and willing to help and got an email of your question.
