Good plugin.

Mike's Stuff Works First Time Every Time
By , for WP 3.9.1

Mike Challis' stuff works first time every time right out of the box. And for my purposes at least, the ease of installation and set up makes up for it not being bullet proof. Don't have a big enough spam bot problem to have to get all technical about a capcha.


Perfect for newbies like me
By , for WP 3.9.1

I am very light user of WP.
I don't know coding, and I don't want to know.
I installed 3~4 captcha plugin to find thing that really work.
And this one is best among other free captcha.
