This site does not require registration or fees for participation. However, it may, depending on need, require the entry of a code word to enable saving edited pages.
We created the code words to discourage robotic attacks. Both the code words and the code word mechanism are subject to sudden change. Our code word policy is to not have a policy. Should the site become subject to systematic abuse, the code word mechanisms will become more stringent. Announcements appear on WikiWikiSystemNotice.
When a code word is presented, you may use it to save edits. This serves the role of a very simple CaptchaTest which probably only works because the rewards for breaking it are so small. There is a MozillaFirefox plug-in that will type the code word for you.
When no code word is given, you may use an alternative code word that floats along among trusted users. There is no way to apply for this code. Try your friends-of-friends network. Remember that this code and the mechanism itself will change if abused.
This server employs a number of self-protection mechanisms which are summarized in MoreAboutWikiAccess. -- WardCunningham.
