I wish to apply the thing used here on my wiki, but can't seem to figure it out. I've looked through the templates and added what I found, and even attempted to look through their MediaWiki but couldn't find anything. I'm able to see the default "Welcome to the ___ Wiki, [Contestant]" on my wiki, but it won't actually show the username. How do I fix this?

Thanks in advance!
