Nookipedia:Signature policy

Signatures are used to sign one's message on a talk page or forum. To do so, four tidles (~~~~) are used. If three tildes are placed, just the signature will be placed, and five will produce the timestamp.

When to use

It is never acceptable to use ones signature on any page other than a talk or user page. Never on an article should you sign your work. Doing so will invoke a warning and the signature being removed. If this happens multiple times, a block will be issued. It is required that one signs comments on a talk page. If you come across an unsigned comment, then use the template {{unsigned}} to sign it. To find out who originally posted the comment, look through the talk pages history. If it was you who forgot to sign your comment, then you still must use the template, otherwise an incorrect timestamp will appear. If you saved the page and fix it a second later, then it is fine to sign normally, but not if another user has commented.
