If the code that you are using is really what you are adding to your preferences, then there's a few things:
 * Your span tags are not closed, which is why you are getting the HTML error. Close them.
 * You are trying to transclude a template which might not exist on other wikias, so expand it.
 * Monobook is not a valid font. I think you mean monospace.
 * And neither of the text links to your userpage or talk/wall. It's really not much of an issue, but I've seen some wikis that have signature policies, so I'd recommend you link your userpage and talkpage too.
