re: Bug 1389
I've just commited a change to CVS that provides a filter that will auto link text with a page name of a wiki in the current course to that wiki. The filter is in the subdirectory 'filter/wikipagetitle'. You need to copy the 'wikipagetitle' subdirectory to your Moodle filter subdirectory.
There is also a language file contained in 'lang/en' called 'wikipagetitles.php' that needs to be copied to the language directory.
If you have problems, I would be very glad if you could mail them.
