[wp-hackers] Advice regarding Custom Post Types and Taxonomies

I gather Posts 2 Posts is a good solution, but if it's not quite what
you need, this plugin might be worth checking out:


There's no UI, but the docs
describe how you can define a custom field for a certain post type,
then populate the field with the posts from another post type. Check
out the basic examples for registering custom fields, then look in the
docs at the 'options_type' and 'options_query' parameters for fields.
