You should strongly consider entering a username in Preferences. This will allow the kwiki to keep track of who changed what page. The username will show up in the Recent Changes page.

The username is saved in a cookie, so it should stay around after you are done with your session. If you happen to be using a public machine, you may wish to clear the username when you are done.

By default Kwiki requires that you create a page about yourself prior to setting your username. So if your name is Eddy Merckz, you should create a page called Eddy Merckz, and describe yourself a bit. Then you can go to Preferences, and set your username.
