Hi, wiki contributors who are looking here!
I recently had to move servers (long story); things seem to have come over fine but the bad news is that the Recaptcha plugin is broken under PHP 5.3.x, which this server is running. See http://code.google.com/p/recaptcha/issues/detail?id=72.
Let me know by email if anything else is busted. You guys should know where to find me.
Testing to see if the patch works?
