To add more rules to your list, open the Validator Preferences: Edit -> Preferences -> Validator -> Tag Checker Rules (2nd tab)
Create new rules
If you want to add your rules to this list use one of the two options:
- Simply create a page in this wiki with your rule, e.g. Rules/MyRuleName. This is similar to Styles and Presets. See there for more information about this topic.
- Externally hosted rule URLs can be entered when editing the RulesSource page.
If your rule applies to a limited area, use Territory selectors, to limit the execution to the area.
