Hi all, thanks for answering on my wall. If you want to know more about how my signature works, please read User:Mathmagician/sig.

Just to clarify, you're not supposed to use cross-wiki transclusion for signature templates. It's O.K. for certain things, such as mainpage footers and user pages. Here are two examples of templates that it is O.K. to transclude across wiki's:
 * A user page template (only appears on your user page): w:Template:User:Mathmagician
 * A mainpage footer template (only appears on the main page of the wiki): w:Template:Animangafooter

However, signatures should never be transcluded across wikis like this, as cross-wiki transclusion is a very expensive operation. In the case of signatures that may be appearing on hundreds of talk pages, that's a very wasteful use of system resources.

The "proper" approach is to make a signature template on the local wiki you will using your signature on. If you will be using that signature template on multiple wikis, then you should copy that template to every wiki you want to have a signature on.
