Thank you for making this plug-in available. It looks very promising. I have my blog set up so that I must approve the first comment from a new commenter. Unfortunately, when a new commenter submits his comment, and correctly answers the CAPTCHA, he gets no feedback saying that the comment is waiting for moderation. He doesn't know if his comment has been accepted or rejected or if there was some technical trouble.
I had been using a different plug-in (which had other problems that forced me to discontinue its use) and it helpfully showed the text of the comment to the commenter with a warning similar to: "Comment pending review by moderator."
Is there any way to get this functionality with Conditional CAPTCHA?
