System messages, also called MediaWiki messages, provide a means for customizing the interface of a wiki.
Please keep in mind that it is not always wise to tweak these messages. The default value is there because it is considered the most universally understandable terminology.
Step by step[]
This system message controls the dropdown of default reasons when deleting a page.
As the messages are stored in the MediaWiki namespace, only admins of a community have the necessary permissions to be able to make changes to the system messages.
For security reasons, not all MediaWiki messages are freely editable. You can see the editable list here: Help:System messages/whitelist. If you want to edit a message not listed there, you must contact Fandom Staff.
Using Special:AllMessages[]
- Go to Special:AllMessages, search for the text that you want to replace, and click the message that uses it.
- If the message has never been edited before, you will see the default message value in the editor. This will help confirm that you are editing the correct message.
- Edit the page just like a normal page, putting in the message text.
Pay careful attention to anything with a "$" in the message. This is a 'variable' that will be replaced when the message is actually being used. You may want to ask for help on the Community Central Discussions if you don't know what these variables represent. - Save the message and verify that the message has changed.
Bypass your browser cache if you do not immediately see the change.
Using the special language code[]
In many cases you can use a special language code to find out a message name more quickly. This can be done by appending ?uselang=qqx to the URL (see this page as an example). All the messages on that page will then be replaced by the names of the pages in the MediaWiki namespace.
