Of course, the question was protected by the Community user, which ups the requirement that is needed to post an answer. However, I've got 109 reputation (I've posted one question, and one answer (+1/-1) so I shouldn't be banned for anything), but I can't answer the question.
I assume this is a bug. What's going on?
