Please do not leave a username warning template on a user's talk page and then immediately report them here. Either discuss it with the user, or report it for admin action, but don't do both at the same time.
Real names are permitted except when they imply that the editor is a specific living person they are not.
Wait until the user edits. Do not report a user that hasn't edited unless they are clearly a vandal.
Do not report a username unless it has been used in the last2–3 weeks. Older accounts are likely abandoned and reports of such users will be summarily declined.
