BuddyPress.org

@bryceburk Actually, if you don’t need social networking, you can do this in WordPress alone. You can use custom post types or categories for countries and states and those are searchable. Users can add posts or custom post types from wp-admin or from front end via

If you want to use BuddyPress – there’s http://buddydev.com/plugins/bp-simple-front-end-post/ where you can created different forms which you can configure to contain what you need. Needs PHP and HTML/CSS skillsets for this though.

There’s also the premium Gravity Forms plugin which can work for both WP and BP.
