Answer 5

Have you thought about placing an asterisk/arrow/some other notation by the choice of your choice for your answer?. When you post 12 or more question and place the answers AT THE END, we must scroll down each time, look at the answer, scroll back up to see what it said etc. It's so time consuming. I agree with 1 and 2 but I didn't look at the others.
