How to markup external links like Wikipedia does?
It would be nice for some applications (at least mine ;-)) to show READERS (unfortunately the majority in most Wiki-installations): this link is an external one. Similar as the question mark shows empty internal links. Maybe, there’s already a function implemented. If not, I can try to write such a markup with my limited PHP 4 experiences. –Armin Made it. Changed a function inside pmwiki.php (I know, not a nice way). Results can be seen at: http://www2.100mb4free.de/sonja/pmwiki/pmwiki.php?n=Blg.Main (well, in German, but easy to understand what I mean). I can post the source if there is any interest.
