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=".
