[Air-l] Free service: protect your Web forms against SPAM

[Ulf-Dietrich Reips]

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.

Ulf & Frederik
