This contact form uses the browser build in form validation (html5) and some of the new css3 functionality. This may mean that some minor browsers might not support all the functionality (right now). Since bots break every captcha code i made a simple human test which you can use to ask a question your target group will know. This might look simple but its the best way to keep the spam bots away.
Please, feel free to give me feedback or suggestions or send me your language pack so i can add it.
Also feel free to donate :).
