following up on Peter's very valid comments, here's a few suggestions: 1) as Peter suggested, instead of using a captcha, ask a simple question with multiple answers, then on form submit check that the answer is correct. the question can be anything, even as silly as "What sound does a cow make?: Meow, Woof, Moo, Chirp"
2) another option, a bit more complicated, is to require user registration before allowing them to post comments. this approach does have a benefit: someone who would have posted a silly/non-essential comment may not want to go through a registration process to do it. on the other hand, a user who actually has something to say and really wants to say ti would not mind registering to do it. 3) as for html in responses - it is pretty simple. there are numerous WYSIWYG editors out there that are relatively smply integrated into your site. FCKEditor (bulit into CF8), TinyMCE, MarkItUp are just a few to name. With all of them you can configure which formatting options to allow your users, as well as many other features including cleaning up text pasted from MS Word, removing illegal markup and offensive words, etc etc etc hth Azadi Saryev Sabai-dee.com http://www.sabai-dee.com/ bill turner wrote: > Hi All, > > I need to create a "reply" or "comment" form whereby individuals can respond > to article postings.
