[pmwiki-users] group name aphabetization

[adam overton]

hi there

i'm wondering if anyone has any suggestions for a special case of  
pagelist alphabetization...
for the site, users come and name new groups using their own name, so  
that we've got a list of groups like so:

Groups:
Jane Moe
John Doe
Albert Foe

etc

at the moment, if i use pagelist and order=name, then the list turns  
out ordered by first name:
Albert Foe
Jane Moe
John Doe


my question: is there an ingenious way to alphabetize group names via  
the last word (which will in this case usually be the last name?) so  
that i get:
John Doe
Albert Foe
Jane Moe


?
thanks!
