Masthead = place on your user profile which displays your username, user rights beyond the normal user, place you live, wiki's you edit regularly.

A script is used to make a certain repetitive action standard throughout the wiki. Those scripts, which are very common in use by the majority of more advanced wiki editors, can be inserted in various points in a single wiki, and can also be inserted wikia wide.

What you need is the script which eladske pointed towards, change it a bit to your likings and insert it (do state in the description when you make a page where you found the source of your script, this is a hard requirement Wikia has, ALWAYS state sources from things you haven't made yourself and ALWAYS give credits to the original creators for their work).

However, this script is a highly advanced form of changing parts of your wiki and requires you to have admin user rights on the specific wiki you want to change. You can implement it, but you are recommended to understand the material before doing so. If you can't do it yourself, you might want to ask others to help you out and do it for you. However, that limits your ability to work with it if you don't understand how it works.

So to cut it short:

Do you need it, are you willing to put in effort to understand it, or can you live without it?
