I will be without reliable internet access starting this Friday, 7 May. Would one or more of you regular posters in the Nature forum please start the Monday in Nature threads for 10 and 17 May, and the Nature Unlimited thread for 14 May? Your assistance is sincerely appreciated. I find it works best to start the thread the evening before, which accommodates users in most time zones. I should be able to start the threads again before Friday, 21 May. Your assistance and support are sincerely appreciated. Happy trails, David.
