So whats the story ?
I have it switched on in the preferences and it does not work no matter which method I choose.
By the way whats a category and whats a representative ? And while we are at it why is there user groups but no users and also is it possible to set it up so it is possible for  normal site visitors to open a ticket without logging in or setting up an account.

Thanks very much Hummdis
Your reply to my main question regarding Captcha was exactly correct.
Never mind the other dumb questions I asked.
I figured most of them out I think.
Its a good system
Thanks again
