This extensions works exactly as advertised. Very easy to set up. No problems or hassles. When I had a question (which was my own fault for not seeing) the developer Christopher replied right away. Highly recommended!
I am very happy with ALFcontact. Setup was a breeze, the features offered are very nice and easy to change, and the way it looks on the frontend is simple and elegant. I would recommend using Bigocaptcha since it looks better than recaptcha.
