Consider creating [[MetaWikiPedia:Template]] for text that is often used. Templates could be used to make menus, headers, and footers. The main WikiPedia use them a lot. For example: [[MetaWikiPedia:Template:H:f_Help|Help Footer]].
Some [[:Category:Template|common templates ]] here are:
:*<nowiki>{{stub}}</nowiki> which marks a page as being a stub and lists it in the [[:Category:Stub]] page.
:*<nowiki>{{cleanup}}</nowiki> which marks a page´s layout as requiring attention.
