Example eprint document with discussion spaces - note the links appended to the document's abstract to public and private discussion spaces. These are processed by the D3Eprints server. If the public discussion has already been created, you are taken to it. If you are the first person to request to see it, then it is created. If you ask to create a private discussion then you are taken to the web form where you can define your own discusion threads, and are assigned full moderator status over a unique URL that is emailed to you.
