Hello, Uw-warn. When you revert a user's changes, like you did earlier, don't forget to leave the user a message on their talk page, especially when reverting vandalism or a test edit. You may find Template:User talk page warnings/table useful when doing this, to let them know that the change was considered inappropriate, and to direct them to the sandbox. Thank you.
This template is used by the standard installation of Twinkle. If you are planning to make major changes to this template or nominate it for deletion, as a courtesy, please notify Twinkle's user base and maintainers at Wikipedia talk:Twinkle.
Please refer to the index of message templates before using any template on user talk pages to warn a user. Applying the best template available for your purpose may help reduce confusion from the message you are sending.
This template uses a parser function. To give greater detail to your message, you may add the article and some additional text to the end of the template. If such article or additional text includes a URL or anything which includes an equal sign ("="), it may break the parser's function unless you prefix the article or the text with "1=".
