Hi all, we would like to announce our free service that easily protects Web forms against spamming by implementing an easy way of including human-readable images as a gate to the Web forms: http://www.onlinemethodik.net/captcha/captchalinkgenerator.php Maybe you have seen Web sites where you could only advance to the next page by typing text that was displayed in an image. Maybe you wondered how to install this on your own site, because you were plagued by SPAM entries to your Web forms (like we were in our web experiment list at http://genpsylab-wexlist.unizh.ch/ ). Now you can protect your forms by simply using a modified URL on pages leading to the form you would like to protect. Please help distributing the information about this free service and send it to colleagues and friends who might be in need of this solution.
