A word of advice: Message boxes are bludgeons, and your users are people who don’t enjoy being bludgeoned.
I have seen days like this: Nov 29 Uncategorized
I just reinstalled my web server from the ground up. Consequentially, rather than hack MediaWiki into something secure, I’m choosing a new wiki.
The current leading contenders are Confluence, and WikkaWiki. Confluence is used both my work and my wife’s work, so learning how to administer it could be useful. That said, I think it’s stupid for any web application to require Java. Until someone gets the Java libraries into a decent distributable with a comprehensible naming scheme, I will remain disinclined to waste my free time with products that rely on it.
Ironically, WikkaWiki uses Java too. But the tasty goodness of built-in MindMap display makes up for the reliance on Java.
In contrast all that Confluence has to offer is a robust framework and good security.
Otherwise, PHPWiki is the obvious choice. Never-mind the history of security breaches. The two words ‘PHP’ and ‘Wiki’ belong together, well distanced from words like ‘secure’ and ‘must recompile to make even minor changes’.
UPDATE: I finally went with DokuWiki.
