So the only problem so far is that just by clicking on the post title I get a message at the top that tells me my answer to the captcha question is incorrect. Of course I haven't even been prompted to answer a question at that point, so maybe I'd be puzzled. Now, at the bottom of the post page I want to leave a comment so I've entered my answer to the captcha (a simple math question) and am about to post my comment. We'll see what happens!
