- ^ While formally Wikipedia:Verifiability and others of Wikipedia's content-controlling policies do not apply outside the main namespace, they must be strictly followed here, for the sake of scholarly discipline:
- The listed event and its date must be mentioned in a wikilinked or externally linked reference. It is advised to consider an external link to a specific version of a Wikipedia page rather than a wikilink, if this page is linked for a critical but volatile piece of information.
- Credible sources must be used only. Within Wikipedia, Wikipedia Signpost is one of them.
- Trivial events must be avoided:
- Random mentioning of Wikipedia belong to WP:MEDIA.
- Routine Wikipedia activities, such as a promotion of an article to featured state, are generally not listed here, unless such events generate significant buzz outside its normal working scope.
