Wikipedia:DRN Rule B

Here are the ground rules for any mediation that is conducted at DRN where the moderator specifies Rule B:
 * 1)  Be civil and concise.
 * 2)  Civility is required everywhere in Wikipedia and is essential in dispute resolution.  Uncivil statements may be collapsed.
 * 3)  Overly long statements do not clarify issues.  (They may make the author feel better, but the objective is to discuss the article constructively.)  Overly long statements may be collapsed, and the party may be told to summarize them.
 * 4)  Do not report any issues about the article or the editing of the article at any other noticeboards, such as WP:ANI or Arbitration Enforcement.  Reporting any issue about the article at any other location is forum shopping, which is strongly discouraged.  Any old discussions at any other noticeboards must be closed or suspended.  If any new discussions are opened elsewhere while discussion is pending at DRN, the mediation at DRN will be failed.
 * 5)  Comment on content, not contributors.
 * 6)  The purpose of discussion is to improve the article, not to complain about other editors.  (There may be a combination of content issues and conduct issues, but resolving the content issue often mitigates the conduct issue or permits it to subside.)  Uncivil comments or comments about other editors may be suppressed.
 * 7)  "Comment on content, not contributors" means that if you are asked to summarize what you want changed in the article, or left the same, it is not necessary or useful to name the other editors, but it may be important to identify the paragraphs or locations in the article.  It isn't necessary to identify the other editors with whom you disagree.
 * 8)  Discuss edits, not editors.  This means the same as "Comment on content, not contributors".  It is repeated because it needs repeating.
 * 9)  Do not edit the article while moderated discussion is in progress.  If the article is edited by a party while discussion is pending at DRN, the mediation at DRN will be failed.
 * 10)  It would be better not to discuss the article on the article talk page or on user talk pages while moderated discussion is in progress, because discussion elsewhere than at DRN may be overlooked or ignored.
 * 11)  The moderator may not have any background knowledge about the subject.  It is the responsibility of the editors, who are familiar with the subject matter, to inform the moderator about the subject matter, just as the purpose of the article is to inform the readers about the subject matter.
 * 12)  Be specific at DRN.  Do not simply say that a section should be improved, but tell what improvement should be made.  Do not simply say that "All viewpoints must be discussed", but identify the missing viewpoints.  If you say that the article has BLP violations, specify how they can be corrected.
 * 13)  This rule permits the editors to engage in back-and-forth discussion, which in turn requires that there be a certain amount of good will between the editors.  The moderator will ask the questions, and the parties may discuss the answers.
 * 14)  Every participant is expected to check on the case at least every 48 hours and to answer questions within 48 hours.
