Ehh... that's a default system message... I may be able to change it.

If you're not like me and have cookies disabled, Wikia will keep you logged in wherever you go. In that sense, you have been detected on that wiki. It would be extremely annoying, especially if you hit the "random wiki" button, for it to tell you you earned an achievement just for being logged in and viewing a new wiki. So, it only occurs when you make an action that it considers a "contribution."
