Script Summary: Automatically fills in the code word (CAPTCHA) “567” on the edit page of the C2 wiki, WikiWikiWeb.
When you edit a page on the [C2 Wiki](http://c2.com/cgi/wiki), such as when you [edit the sandbox](http://c2.com/cgi/wiki?edit=WikiWikiSandbox), you are asked to type a code word. As far as I have seen, that code word is always “567”, and it will probably remain that way as long as nobody bothers to spam that wiki. This user script types in the code word for you whenever you edit a page so you don’t have remember to type it or bother to decode the message telling you what the code word is.
