texte = Just a thought on the CAPTCHA code--I had been looking around a few months back for something like this, whether in WebDNA or not, and I discovered a very simple approach that someone had taken whereby they simply added a field to their form, set the style of the field to hidden so it was not seen by anyone but the spambots (since they generally don't "understand" CSS), and will invariably enter some value into the field. Then, just check to see if that field contains anything, and if it does you know it was filled in by the spambot so you can reject it. So far this has worked well for me although there may be something I am overlooking or maybe all the spambots that have hit my sites have been of subpar intelligence. Anyone care to weigh in on that as to why it wouldn't work in some situations? -- ** NOTE NEW VOICE NUMBER ** Gil Poulsen, Mac Wirehead ************************ AltiM@c Consulting 23 Marco Polo Court Franklin Park, NJ 08823-1703 Voice: 609-359-0103 http://altimac.com ************************ ------------------------------------------------------------- This message is sent to you because you are subscribed to the mailing list
