in order to better keep spammers at bay (and to lessen my workload deleting spam) I have added the reCAPTCHA service to the forum entry form. It makes it slightly less inconvenient to post messages but it also makes it far less likely that you have to endure spam.
A CAPTCHA is an acronym für Completely Automated Public Turing test to tell Computers and Humans Apart. It works by requiring you to decipher a distorted text which an automated OCR program hopefully fails at.
One nice twist with reCAPTCHA is that they use this input to help digitize books. Another one is that the site still stay accessible even for blind users since it also can provide audio challenges.
I hope reCAPTCHA isn't too hard on you. Otherwise, let me know and we will see what we can do.
