Hope this helps? Thank you John, this helps a lot - more 'findable' is
what I was after especially as most offending page names are

I have implemented this and it works great however, I had to do one
other change to the new function.  I had to comment out the following

    if (@$MakePageNameFunction)
        return $MakePageNameFunction($basepage,$x);

... otherwise I got a 'content-length: 0' at the browser.  I think it
was an infinite recursion.  Have I done this correctly?

So for completeness and a single point of reference, this is what makes
PmWiki pages more 'findable':

1. Copy the attached altmakepagename.php file to your cookbook dir

2. Add the following to your local/config.php:

       $MakePageNameFunction = 'AltMakePageName';

3. Check permissions on your new file et. al.

Thanks again for your help John, couldn't have done this without you.
