On runbot, the demo of Odoo 10c shows that you could have a page /partners (for resellers) and a page /customers (for customers). It even adds it to the footer of your website. These require to have the proper modules installed. Did you make sure to have these modules installed: website_partner, website_customer, and website_crm_partner_assign. It is website_partner that will add a link in your website's footer and create the /partners page. The other modules add features on top of that concept.
Test these in a test DB first to only install the modules you need.
Is there a "partners" page that I can add to the main menu?
