First off, this is an awesome plugin and very easy to use. I've installed it in over 15 sites I've developed. One issue that was pointed out to my by a programmer friend of mine is that it causes the "RealSimpleCaptcha" plugin to not work which leaves certain security holes open. I don't know what they are all I was told was to remove it.
I really don't want to so I figured I'd ask if there is any way to sort this out.
