(My final request... honest!)
I have looked into this but cant find a definitive answer. Is there any method available to use custom fields and for post types and have these value link (like taxonomies) to a page that aggregates all matching values.
I am currently using taxonomies to do this (and I can continue to do so) however I am missing some of the flexibility of Custom Fields by doing everything with Taxonomy.
Can custom fields be used to link post?
