The banner displayed on protected questions still states that the reputation threshold for answering is 10, but the real threshold appears to be greater than 75. I have 75 reputation on Stack Overflow, all of which was earned on Stack Overflow, but still can't answer questions there for which protected is the only restriction.
Should I be able to answer protected questions, or is the content of the "protected" banner out of date?
EDIT: Here is a link to a question affected by this issue:
