[pmwiki-users] Pagelist ordering by name

[Vince Admin Account]

Patrick et. al.
My profiles group is set up with titles being full names, i.e.,   
JohnSmith for example.
I would like a pagelist to format the output by adding a space, and in  
order of last name. Currently it does neither.
I suppose I will have to write a custom order function, and I don't  
know how to add the space in the template either. Any suggestions as  
to where to look.
Thanks,
      Vince
