We got a report today that someone was having trouble getting past the CAPTCHA on our submission form, so I looked into it and the problem was related to a change I made last week. Some readers may remember that we had a rash of spam comments on the site last week and as part of the effort to curb that bullshit, I ramped up the security so that reCAPTCHA challenges were case-sensitive. I'm not sure why, but that made it impossible to correctly answer.
reCAPTCHA is a robust service used by millions of sites, so I can't imagine that their system is just totally broken, but it definitely screwed things up for us. So, if you've been trying to register a new account or submit a score or story for DNN, please try again! Sorry for the inconvenience. -G
