Scenario: I've got a "main" page with links to a couple different parts of my site, including a PunBB install.  I'd like to include the most recent posts from a particular forum as "site news" on the main page.  I'd prefer to leave the "main" page as .shtml rather than get PHP involved...

So I tried: 

<!--#include virtual="board/extern.php?action=new&show=2&fid=3" -->

straight from the docs.

Result:  This gets inserted where I expect the news to show up --

So I tried it in a separate file, with "action" set to "stats" or "online".  The output was the same kind of gibberish.

Is this some kind of encoding issue?  The language is English all over, so I wouldn't have expected any problems...
