Nice!

Am using this plugin for login, registration, and password recovery forms, and it works great! It’s much too involved and demanding to enable on comment and contact forms (where I use other captcha plugins), but that’s what I was looking for — something more robust on the pages that grant site access. I’m very happy with how this has been working for me.

*Suggestion* — I love the ability to choose the type of operations (multiplications, divisions, etc). And, I love that the solution isn’t always at the end of the equation (e.g.: 7x?=21). That’s really great. I would also appreciate an option to select the number of operations. That is to say, the ability to enable more complex (multiple-step) math equations, such as 3x4+6=? — so, choosing 2 steps, 3 steps, 4 steps, etc. Not a deal-breaker by any means, but I feel it would make the site that much safer knowing it requires thought and intelligence to get beyond the login screen…

Overall, many thanks for this plugin!
