Help:User and user talk pages
User pages allow users to create content about themselves and/or create to do lists of things to do on Wiktionary.
To avoid having a lot of content on a user page, a user can use subpages. These are done using a forward slash (/) after the full user name. For example, User:Example/subpage is a subpage of User:Example. User:Example/Subpage is a different title, as Wiktionary titles are case-sensitive
The technique is also used for use talk pages, chiefly to archive old discussions without deleting them entirely.
