These users have write permission to pages on this wiki, by default.
For the moment, this page is world-writable so WG members can change the way their names are written before they get an account, and so new WG members can add themselves. We'll start to enforce real access control to this page if it becomes necessary.
If your name is written as a WikiName (like GuusSchreiber), then it becomes a link automatically. If you would rather have your name appear throughout the wiki as a non-WikiName (like Ralph R Swick or guus), you and others will have to type it using the slightly more verbose form: ["Ralph R Swick"] or ["guus"].
The names here are links to each user's Wiki home page (which may or may not exist yet).
