[wp-hackers] Adding editing rights for specific posts in a custom post type

[Steve Taylor]

Hi David,

I've found this plugin invaluable:

http://wordpress.org/extend/plugins/members/

What you're describing doesn't sound as if it'll be entirely catered
for by the plugin, but it should help a lot.

Past that, you'll need to understand how you're using the
'capability_type' and 'capabilities' arguments for
register_post_type() (if that's under your control and not exclusively
managed by the plugin. I dealt with this briefly but I forget the
details. Oh, here's an article by the saviour who did the plugin:

Hope this helps...
