Thanks for the reply!
Is Confluence the wiki I was hoping for back in October?! I knew there was already some documentation on it 
I am going to update this topic’s title to reflect its focus on adding services, and would like some further clarification.
What you described, @Agnes_de_Lion, makes the most sense to me. However, before I started this topic I visited https://tosdr.org/en/service_requests and accidentally rejected zellepay.com when trying to suggest a change to its domains.
Is https://tosdr.org/en/service_requests a site I should even have access to? Is it an artifact of past versions, or does it play into the service requests that general members make?
Regards
