A. All user signatures must clearly identify the username of the user, either with a full name, obvious nickname, or obvious abbreviation. For example, User:RandomUser305 could sign off as "RU305."
B. All links in user signatures must clearly identify their targets.
C. Images in signatures are permitted, as long as they do not exceed 30 pixels.
D. All user signatures must not exceed the height of a line of text (unless they are an image), disturb the layout of the page, or be excessively long.
E. Content of signatures must be clearly visible with regard to color schemes.
F. Signatures that contain an elaborate amount of code must use a signature template. Users unfamiliar with this may seek assistance from another user.
G. Administrators reserve the right to adjust signatures to comply with this article.

Weak Support - Not really much of a change, but I still support it. --TOMODACHIDUDE45678 WAS HERE 23:56, November 12, 2018 (UTC)

Oppose - I am against how your signature has to have your username in it. If somebody doesn't want to have it but have it link to their userpage only to identity them, then why not? 1033Forest (talk) 00:01, November 13, 2018 (UTC)
Comment - I would like to say that this is already the rule, but we are making a minor change that specifies the rule more clearly. Not much of a change is happening here. Anthony2306(W•C•L•E) 00:12, November 13, 2018 (UTC)
Comment - We want everyone's signature to at least somehow reference their username to prevent confusion. — AMK152 (Wall • Contrib) 00:14, November 13, 2018 (UTC)
