I've looked at hn_captcha already and that's also under the GPL license. cm_freecap is the one I'm using at the moment - I'm really pleased with it but need to replace it because of the licensing issues. VeriWord looks more interesting, it's not under any license and from the description it sounds quit good, I'll investigate this further. Thanks again. ********************************************************************** This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.
