Template:Uw-redcat
Before adding a category to an article, please make sure that the category page actually exists. In some cases, it may be appropriate to create a new category in accordance with Wikipedia's categorization guidelines, but it is usually better to use the most specific available existing category. It is never appropriate to leave a page categorised in a non-existent category, i.e. one whose link displays in red. You may find it helpful to use the gadget HotCat, which tests whether a category exists before saving a change. Thank you.

To customize your message, parameters are available; one to add the article name, and one to add additional text at the end of the message. If your param value contains an equal sign (as urls often do), then be sure to explicitly specify the positional parameter by number; i.e., use |1= or |2= followed by the value; e.g., |1=XYZ=Repainting.
