When posting to this forum, we encourage you to converse as you would if you were having a live conversation. In other words, please avoid very short answers and always feel free to expand on your points of view - just as you would if you were chatting to a group of friends. And, just as you would if you were talking in a group, you can respond to the other comments already posted, not just the question! Please try to avoid very short posts such as "I agree with Joan" - please always try to add value to the conversation by expanding on why you agree - otherwise it's very easy for the conversation to devolve to a series of one line comments, which is simply not interesting to read. If you feel there's a topic that you'd like to discuss but you can't because the present topic headings don't cover it, you can create a new topic by clicking the "New Topic" button at the top of the page. Thank you!
