Welcome to Wikipedia. I noticed that your username, "Example-bad-username", may not meet Wikipedia's username policy. If you believe that your username does not violate our policy, please leave a note here explaining why. As an alternative, you may ask for a change of username by completing the form at Special:GlobalRenameRequest, or you may simply create a new account for editing. Thank you.
The notifier has not provided a reason why this username violates the username policy. If you do not understand why your username could be inappropriate for Wikipedia, please remove this message and leave a message on the notifier's talk page requesting clarification.
Template documentation
This template is not for blatant violations of the username policy; it is only for edge cases or questionable usernames.
Report blatant violations to Wikipedia:Usernames for administrator attention.
This template should always be substituted (i.e., use {{subst:Uw-username}}). Any accidental transclusions will be automatically substituted by a bot.
If you plan to make breaking changes to this template, move it, or nominate it for deletion, please notify Twinkle's users and maintainers at Wikipedia talk:Twinkle as a courtesy, as this template is used in the standard installation of Twinkle. Thank you!
Usage:
{{subst:Uw-username|Reason}} references a specific reason
{{subst:Uw-username|Reason|Additional text}} adds text onto the end of the message instead of "Thank you"
This template conforms to guidelines organized by the user warnings project. Please discuss the general visual appearance of these templates (for example, the image in the top-left corner) on the user warning talk page.
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.
Please remember to substitute the template using {{subst:Uw-username}} rather than {{uw-username}}.
This template uses a parser function. To give greater detail to your message, you may add the reason and some additional text to the end of the template. If such reason or additional text includes a URL or anything which includes an equal sign ("="), it may break the parser's function unless you prefix the reason or the text with "1=".
