I was using another (commercial and not commercial) components before but i missed some features and compatibility issues and so i switched to proforms. The best feature for me are the better and nicer captcha-settings. In the first days of usage i had some difficulties and wrote a message to the proforms team. They replied very fast and helped me to solve some things in a very kind way. As they are from Germany, i can write in german, and so i´m not having any problems to describe my needs in another language. Thumbs up for this great component - to a very good price/performance ratio!
