You could do a few simple tests to detect how spammy a wiki edit is and only require the user to enter a captcha if the edit smells spammy.
The wordpress plugin "Spam Karma" uses this approach and has been very successful at stopping spam on my blog. _______________________________________________ pmwiki-users mailing list [email protected] http://www.pmichaud.com/mailman/listinfo/pmwiki-users
