Forum:What's wrong with the Captcha? (bis)

Apparently other users have the same problem I'm facing: the CAPTCHA on the registration page doesn't accept my answer. It says "Incorrect or missing confirmation code", but I'm positive the answer is "rationalwiki". BTW, I have the same problem when I want to edit a page as unregistered user. Any help here?

For those facing the same problem: you just have to try 33 times. Just keep trying, and ultimately it accepts the code. @Webmaster: can something be done about this?
