Directory Plugin Form Fields/Taxonomy


I purchased the Directory plugin and am having some trouble setting up the form fields. I’m attempting to remove the “title” and “content” boxes that are included by default and replace them with my own custom taxonomies. But I’m unable to do so- also I would like the taxonomies to by searchable by users through the “Taxonomy Picker Plug-in”. Currently only the default “title” and “content” are searchable but not the taxonomies that I set on my own.

How can I fix this?

One other question- How can I go about making it so that non-users (anyone who visits the site without making an account) can make a post?

Thank you,
