While I always encourage discussion in other forums, this one is a little different... The idea here is that questions can be posted here, and they may not get answered right away (if at all.) It is as much a place for ideas as anything, not a forum meant for discussion. If you wish to have a discussion on an issue that isn't in one of the existing courses, please use the "General" forum, not this one. Posts in this forum beyond the original poster's questions should be only for clarification and may be removed. Thanks for understanding.
