I was also thinking of creating a contact-the-seller e-mail form with a captcha.
I found these codes which I think are pretty good to go on, but I would like the recipient to be specific. I think if you somehow can link the recipient to the e-mail column.
Also I dont know, but the captcha isnt working. I get nothing showing. Dunno really
this is the mailto.php and it sends to vasplusCaptcha.php
