First of all thanks to Michelle from this list I finally found out how
to easily change the navbar/navbox. Since other people on this list
seem to be confused about this same point I will post how to do it
again. When i get a change I will add this info somewhere to
wikimedia though I'm not sure where is a good place.
Let wikiname be your wiki's name, i.e. things in the project namespace
are of the form wikiname:whatever.
Go to wikiname:All system messages . This will be a very long page.
Search for the entry on the navbar that you wish to change. For
instance if you wanted to change 'Community Portal' search for this.
You will be presented a link to change the text displayed (in the case
of community portal the variable is just portal). Nearby is another
link to change the url, usually the variable name you just
changed-url.
I'm not sure how to add *new* links. I think you may need to go out
and edit SkinPHPTal.php and xhtml...stuff.
WARNING: These changes will not take effect immediatly. After I made
my changes the very next page I displayed was updated but after that
the change did not show up on later pages for another hour or more.
This was what caused me so much confusion.
