I gotta say, that captcha is a real nuisance. The codes are practically illegible and half the time I get them wrong. When that happens, the page refreshes with an error message and a different captcha -- as well as reverting all the changes you made in the editing window. So, you have to go back to the previous version of the page, copy the text and paste in the new window -- and hope that you get the codes right this time. X(
Is captcha is really necessary for logged in users?
