Edit filter configuration

The edit filter can identify and prevent potentially harmful edits and other activities. Important notes:

• 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 which 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. Please test filters before enabling any actions. If you are not sure about something, please ask for help.
