The MediaWiki software that runs the Sonic Retro Info Wiki keeps track of every edit that is made to every page. It also tracks who made the edit. Therefore, it is possible to search and discover what edits a specific user has made on Sonic Retro. There are several methods of doing this:
You can also make a link to a specific user's contributions list (either your own or someone else's), by including [[Special:Contributions/USERNAME]] in the wiki text.
The list of edits is presented in reverse chronological order (from newest to oldest). There is one line per edit, showing the time, date, an "M" if the edit was minor, the page name, and the edit summary. (There is no note included if the page was newly created.)
If an edit is marked "(top)", that means that that edit is the most recent for the page in question at the time the list was generated. Administrators also have a "rollback" link on these lines. (See Help:Revert a page.)
Edits for deleted pages will not be shown in this list, because those edits are no longer part of the database. (But undeleted pages will be restored to the list of contributions.) The act of deleting or restoring a page is also not shown in the contributions list (if the user is an administrator).
