Well, I was not expecting pmwiki to 'know' which groups. ;)

I was looking for something that a user could use when
creating the link itself, similar to what you did below,
but without requiring skins/CSS to change.

  But since you mention it, in this particular case, having
a group that can be set to not display the '?' without
author intervention would be helpfull, so I cooked up this

This allows an admin to define a group in config.php like this:

$LinkPageCreateGroups["AllInOne"] = FALSE;

which will not have '?'s displayed.

(AllInOne being the group with only a GroupFooter in it).

Agreed, a little complex for general use, works for me in
this case.

This is nice, but for the case of non-existant group
homepages in pagelists it would be nice to do this without
CSS mods. Something similar to 

   %noquest% GroupB.NonExistentPage

but maybe more like
