Hmmm well I am not sure that I exactly need a wiki but what I need is a place on my site where anyone can write a post (after probably image authantication) and others can comment on it(if they want). So it's more like wiki/forum where people don't need to register and they can write there reviews or whatever they want. Is there any tool/script for this ? I have some CMS's provided my host but I am not sure how to use them. I don't want too complex stuff, just the simple basic stuff. I don't think so that mediawiki(which powers wikipedia) is right for me. Regards
phpBB offers a CAPTCHA system (image authentication), and you can set it so that anyone can post. www.phpbb.com -Tony
You can download and use WikiMedia CMS for free. It is the same CMS that Wikipedia uses and it's OpenSource.
