Tardis:Signature policy

Our signature policy governs the use of user signatures on this wiki.

How done
Users may "sign" their comments by typing four consecutive tildes ~. This action will trigger the display of whatever is in the signature line found at Special:Preferences. If you have opted to create something fancier than the default configuration — either by introducing new code directly into the signature line at Special:Preferences or by calling a template — then your code must be functional to the following extent:
 * it must create a clickable link to your user page
 * it must create a clickable link to your user talk page

When required
This wiki forbids users from adding their signature to a page in "normal" article space. But it requires users to sign their posts on talk and forum pages, except in the case of the discontinuity index, where signatures are optional. This exception derives from the fact that the discontinuity index was formed by taking material directly from the main namespace, where signatures are prohibited. Thus, thousands of comments appear in the discontinuity index without signatures, without a realistic hope of them ever being added.

For those wishing a more precise wording of the policy:
 * signatures are required in all odd-numbered namespaces, as well as 110, 112, 500 and 502.
 * signatures are prohibited in all even-numbered namespaces, except 110, 112, 500 and 502
 * signatures are optional in the discontinuity index and on your own user page.  You may put your own signature on your own user page, but you may not put it on someone else's user page. (Please note that user pages, in namespace 2, are different from user talk pages, in namespace 3.)

What to do if you encounter unsigned comments
From time to time you will run across unsigned comments on a talk page or a forum page. It's recommended that you don't post replies like "Sign your posts, dude". Instead, forum consensus compels you to make an effort to help identify unsigned comments as they are encountered. This can be done by using the following markup: and By putting in one of these two templates, you'll create a message like this:

which will more subtly indicate that a signature should've been added while positively identifying the poster who failed to sign.

What your signature should look like
As of June 2011, this wiki has never set down any limitations as to the visual look and design of signatures, despite the fact that such regulations are commonplace on Wikipedia and other Wikia wikis.
