Just a suggestion, but you may want to consider adding a way for users to generate new Captcha's on the Model/Voting pages. I know the Beta is shut down for the week, but I encountered a situation where it would not accept the text I entered, despite it being clear as day what the Captcha was. I tried other text anyway, but it was still rejected. Having the ability to refresh the Captcha would be beneficial if this happens again, rather than be forced to Refresh the entire page.
