====== User Pages ======

This is to have a namespace that is for user pages, where each user has AUTH_EDIT on their own page, without the need to add an entry for every user to the ACL.

This patch has been applied after the [[:tips:Separate Admin Login]] patch:

This is a hand-hacked version that doesn't require the other tip to be applied (you may have to fix it up):

If you want the users to create their own user page you must change the AUTH_EDIT on the line
<code>
if($id == 'users:'.$fullname) { $min = AUTH_EDIT; }
</code>
to AUTH_CREATE, like:
<code>
if($id == 'users:'.$fullname) { $min = AUTH_CREATE; }
</code>

This other version use the user login name instead the user name, and also grants create permission for the owner user.
