Welcome to the Edit Filter management interface. Using the Edit Filter, authorized users can configure a wide range of tests, which may help identify and prevent potentially harmful edits and other activities before they are added to the wiki, and the automatic actions to be taken.

Important:

• Make sure you're familiar with the guideline before creating or modifying filters.
• PLEASE be careful. This is potent stuff. Unless it's urgent, always test your filters with no actions enabled first.
• The examine and test interfaces are awesome for learning the ropes. They let you look at specific edits and filters in detail, without risk of disrupting the encyclopedia.
• Keep an eye on the log.
• For guidance on how to use tags, see Wikipedia:Tags. Don't forget to define their appearance and description.
• There is a bot reporting users tripping certain filters at WP:AIV; you can specify the filters here.

Please be careful when creating or modifying a filter. Even a single typo can potentially disrupt the editing of thousands of legitimate contributors. It is strongly recommended that you test your filters first before you enable any actions. If you are not sure about something, please ask for help. If you cause problems, you may have your edit filter manager permission revoked.
