This page is a hard rule on the Simple English Wiktionary. Many people agree with it. They see it as a standard that all users should follow. When changing the page, please check that the other people agree with your changes. Use the talk page when you are not sure or when you want to propose a change.
Wiktionary is not an encyclopedia, a genealogy database, or an atlas; that is, it is not an in-depth collection of factual information, or of data about places and people. If you are looking for an encyclopedia, try Wikipedia. Wiktionary articles are about words. A Wiktionary entry should focus on matters of language and wordsmithing: spelling, pronunciation, etymology, translation, usage, quotations, and links to related words and concepts.
Wiktionary is not paper. Thus, Wiktionary effectively has no size limits, can include links, can be more timely, etc. It also means that the style and length of writing appropriate for paper may not be appropriate here.
Wiktionary is not a soapbox, chatroom, or discussion forum. Although there are many discussion pages in Wiktionary, they are just to discuss about making Wiktionary better, which is our goal.
Wiktionary is neither a “mirror” nor a repository of links, images, or media files. All content added to Wiktionary may be edited mercilessly to be included on the site.
Wiktionary is not a free wiki host or webspace provider. You may not host your own website at Wiktionary. If you are interested in using the wiki technology for a collaborative effort on anything other than writing a dictionary of all words in all languages, even if it is just a single page, there are many sites that provide wiki hosting (free or for money). You can even install wiki software on your server.
Wiktionary is not a battlefield. Every user is expected to interact with others civilly, calmly and in a spirit of cooperation. Do not insult, harass or intimidate those with whom you have a disagreement. Rather, approach the matter in an intelligent manner, and engage in polite discussion. Do not create or edit articles just to prove a point. Do not make legal or other threats against Wiktionary, Wiktionarians, or the Wikimedia Foundation. Threats are not tolerated and may result in a ban.
Wiktionary is not censored for the 'protection of minors' (content-rated). First, anyone can edit an article and the results are displayed instantaneously, so we cannot guarantee that a child will see or read nothing objectionable. Second, Wiktionary has no organized system for the removal of material that might be thought likely to harm minors. However, articles can be, and are, censored by consensus.
Wiktionary is not a place to test out software changes. If you wish to test out your code on MediaWiki, please do so on Test Wikipedia.
