[xwiki-users] captcha - some progress - stuck now!

Dear All I am trying to get a captcha to work, and am struggling. If i go to edit the register page and edit the code I can get a captcha field to display :-) along with an input box. This is what I did: #if ($xwiki.jcaptcha.verifyCaptcha("CaptchaName")) #if ($context.user=="XWiki.XWikiGuest") <img style="border: solid 1px #000000" src="$doc.getURL("jcaptcha")"> <br /> Please type the captcha below:* <br /> <input size="40" type="text" name="jcaptcha_response" /> <br /> #end #end I have searched through this mail group and read several posts on using this captcha. I have tried altering the action thus: <form id="register" action="captcha.vm" method="post"> but that didn't seem to do much (well, anything really!) I have also tried this http://n2.nabble.com/CAPTCHA-for-comments-and-registration-td507976.html#a50 7976 frm Sachin Mittal at the very bottom - but I am lost! Could somebody please help? Thanks E
