Sorry if you had a problem registering but glad you made it in!
In all seriousness, I just checked all the questions and they're all super simple and straight forward. You probably either made a typo or you wrote a number where you needed to spell it out...like 2 instead of two or vice versa. All the other questions are just fill in the blank like 'The United _____ of America' which anyone should be able to figure out or there's a few basic math questions in there like 9-5+4=__ (answer=8) which again, anyone should be able to figure out. I try and change some of the questions slightly every week because unfortunately spam bots eventually figure them out and then this forum gets inundated with spam. That's the reason for the questions in the first place...to try and weed out most of the spam bots.
