Ok, the very "click" after posting this above, I got it again. In fact, got the double whammy. Did one set of 2 screens, then it made me do it again.
Time to revolt. I say each time we get one, we start a new thread announcing "I'm out for the day due to captcha." Start a new thread every time it happens, leave for the day, and announce that too. Maybe soon there will be enough threads littering the forum that someone will notice and do something. Do they even care if we stop posting for a day when it happens? We might need to find out.
