- Please remember to substitute the template using
{{subst:Uw-badcat}}rather than{{Uw-badcat}}. - 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 a named template parameter. Use "
1=" if the article contains an equals sign and use "2=" if the additional text contains an equals sign (such as a URL). - 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.
