[wp-testers] Question about custom taxonomies

[Andrew Nacin]

Hi,

This mailing list is for alpha/beta testing of WordPress. You may have
better luck on the support forums at http://wordpress.org/support, or
potentially the wp-hackers list, which has gravitated to these kinds of
topics though that isn't the right venue either.

To briefly answer your first question, custom taxonomies have fine-grained
capability controls I would look into. For example authors cannot add
categories, they can only assign them.

For your second question, I have seen a plugin many versions ago that
converted the checkboxes of the category meta box to radio buttons (via JS,
I think), then also make sure that only one category is saved on the
backend.
