 The UserName will show up in RecentChanges and at the bottom of each page as the user who last edited the page. If the corresponding page exists within SL (see HomePages), then your name will also be linked.
 Bookmarks appear at the top in the left (yellow) side bar. They have to be valid wiki links, like the ones you put into square brackets. Hints:
- add "RandomPage|phpwiki:?random=1" to your bookmarks.
- add "Page info & history | phpwiki:?info=_referrer_" or "Latest page diff | phpwiki:?diff=_referrer_" to your bookmarks if you like to access these functions from the sidebar (they are also available at the bottom of every page)
