Questions answered by this recipe
My wiki mainly uses a single group. Is there a way to strip the group name from the URLs?
This recipe makes it possible to omit a "master" group to make your URLs as short as possible. So if your master group is "Emulation" you can use http://www.example.com/MAME instead of http://www.example.com/Emulation/MAME .

Copy it to the directory containing pmwiki.php and apply the patch:
patch < zero_master_group.diff
To make a group other than Main the zero/master group you can change line ~45 of pmwiki.php to
define( "ZERO_MASTER_GROUP", "<group_name_here_please>" );
I would have pulled this into config.php but it is not possible to do this in an easy way.
To prevent PmWiki from automatically "fixing" your URLs by adding the group in front of the pagename you might also want to add
$EnableFixedUrlRedirect = 0;
to config.php .
This recipe is a patch written for PmWiki 2.1.3.
It might work with later versions but is not guaranteed to.
