Dear ALl I was wondering if I am doing something wrong because I have only had a couple of answers to my post about getting a "captcha" into the registration form. (thanks Manfred). I have found reference to "captcha" in the config file, but changing 0 to 1 didn't seem to make a difference (that I could find searching around in the class/properties) Maybe I am posting on the wrong newsgroup? I still need to know: 1 ... is there a captcha opion built in to xwiki somewhere? 2 ...if not, would it be feasible to try and "drop" something like a php version (etc) of one in? I really would appreciate any help that anyone can give with this thanks very much Edward
