>> Mh.. well. I know this problem, too. I leave the Discussion sites open for no registrations, so that visitors can easily write a comment to this specific blog entry without the need for registration. (This would be the same behaviour, as many blogging engines are using). Maybe it is possible to wrote a plugin that would scan the text which is submitted via spamassassin or something similar. (Using this combined with known spam URLs would maybe reduce the load of the server if there are many webpages which are getting editted by someone). If you like this idea Joey I might be interested to write such a plugin after my exams this and the next month. :) -- [[Winnie]]

+You might look at the Wikipedia page on "Spam\_in\_blogs" for more ideas. In particular, would it be possible to force a subset of the pages (by regex, but you'd choose the regex to match those pages which are publicly writable) to use rel="nofollow" in all links.
