The captcha thing is irritating. I run into it almost every time I post, and I don't post a lot of links or quotes. Usually if I'm quoting someone, it's my kids or another relative, and that shouldn't be a copyright issue.
Usually I can solve it by using the back arrow once the first captcha kicks me back to a blank screen. I can recover my text and the second captcha generally works like it's supposed to.
It is irritating, though. Very.
