Wise words. No-one on BF should be afraid of making mistakes. However competent! As a wonderful person once said, "Learn to fail, or fail to learn." A consensus always develops based on available evidence. Please allow no-one here to "have a go", and NOT fear ridicule, because they did a great thing. And did what they could to help someone who needed help. If we fail, at least we tried to help. Everyone who learns to fail here, never fails to learn by their mistakes. A world without imperfections would be boringly perfect. A world without diffuculty, and "left-field strangeness" would be not my world! I celebrate the mistakes of others. Long may I live to be informed of these mistakes. And long may we ALL learn from those of others and, ourselves...
