Yeah I guess the colors are too bright and don't really suite, maybe different color palette? And why is it that we need this Captcha Robot Check crap, there's nothing more annoying or easier to hate. The old forum worked without it and I'd gladly use the old one just because of the Annoying Captcha.
The old forum worked without it because of the incredible amount of work moderators put in cleaning spam up. I'll turn down it's aggressiveness but it's here to stay for new posters (you shouldn't be getting it as you have a decent number of posts).
