think its worth mentioning the use of ifexist for when using templates and you post on multiple wikis yet dont feel like setting up a sig template on each one. use somthing like this Username (talk) basicly checks if the template exists and uses it or not, the alternative on this example is the same as the basic one everyone has, but can also be formatted or can use different template location if one wikia site sig policy requires a specific place to put sig templates.
