Yes, but using a too hard protection where it isn't needed makes people irritated and they will hate your site. If you're using more then 1 CAPTCHA program on a simple board for example. But if you have a site like the NSA, yes, then it wouldn't be very strange to use 10 different CAPTCHA programs. Tijnema

Tijnema: I sent this to Daevid off-list because I was trying not to continue a topic that is not specifically php, but instead deals with a problem that may be solvable/mitigated by a php script (I know very thin thread there to keep this php related). However, I like my dot captcha (been fixed for IE 5 & IE 6) , see: http://sperling.com/examples/dot-captcha/index.php As you can "see", it's only for sighted users. Using that type of captcha coupled with asking questions (such as click the green dot while presenting several different colored dots) and providing several captchas in session to pass, could raise the level of security quite high while not inconveniencing the user too much -- or so I think. Remember, spam bots have no information as to what to present for entry and visual recognition routines would have a lot of trouble with these as my imagination and coding can change with much less effort. It makes for an interesting problem. Cheers, tedd -- ------- http://sperling.com http://ancientstones.com http://earthstones.com
