The signature policy outlines what is expected of wiki signatures on the wiki. This is really important as we need to be able to identify users who respond to proposals for example.
All user signatures must clearly identify the username of the user or link to their profile page. For example, User:RandomUser305 could sign as "RU305." All links in user signatures must clearly identify their targets.
Images in signatures are permitted, as long as they do not exceed 30 pixels. 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.
Content of signatures must be clearly visible with regard to color schemes. Signatures that contain an elaborate amount of code must use a signature template. Users unfamiliar with this may seek assistance from another user.
Administrators reserve the right to adjust signatures to comply with this policy.
