These are templates as used by Wikipedia for auto categorising articles that required editing for various reasons, see http://en.wikipedia.org/wiki/Wikipedia:Template_messages for full information.

Current available ones are
{{expand}} - {{expand|examples and additional citations|date=November 2024}}
{{expand-section}} - {{expand-section|examples and additional citations|date=November 2024}}
{{update}} - {{update|type=section}}
{{cleanup}}
{{offtopic}} - {{off-topic|article}}

I may add Merge / split at some point.

Adding these to a page will auto add that page to one of the following categories;
Category:Articles to be expanded
Category:All articles to be expanded
Category:Articles in need of updating
Category:Wiki cleanup
Category:All pages needing cleanup
Category:Articles with off-topic sections
