Being annoyed with the complexity of existing captcha implementations  
(PStore, temporary files - wtf?), I rolled my own and turned it into an  
easy-to-use webservice: [http://captchator.ruby-forum.com/](http://captchator.ruby-forum.com/)

I only have an example for using it with PHP there, but it’s so trivial  
to implement that any further examples seem unnecessary.

Please tell me what you think.

Hello,

I hope my response will not annoy you.

I am very new to rails and would like to implement your captchator on a  
simple web form. Is there a set of directions for “implementing Andreas’  
captchator for dummies”? I get the basic concept, but I am learning the  
whole ruby on rails thing now and it’s still a bit fuzzy in my mind. I  
was able to get the captchator image to display

Next you say to:

Create or modify an existing form with a text field to send the captcha  
answer to your script. (I’m not sure where or how to do this)

Then:

Your script needs to check the submitted captcha answer for correctness.  
To do so, it loads the following URL from the Captchator server:|  
(where do I do this?)  
|[http://captchator.com/captcha/check\_answer/$yoursessionid/$answer](http://captchator.com/captcha/check_answer/$yoursessionid/$answer)

(and where and how do I do this?)  
If the answer is correct, the result is “1”, if not, it is “0”.

Any help you could give would be VERY MUCH appreciated.
