Forum:Consensus on page naming.

I am curious as to the naming conventions. There are a number of pages that have (Earth 616) in the page name but when I try to link to that page it does not seem to work effectively. Specifically I created the page for the Spaceknight named Ikon that appeared in The Annihilators #1. However in editing the page for issue #2 it seemed silly to have to add the (Earth 616) to the name while other characters did not require it in the link. I am trying to input the history of the Spaceknights and there three seperate generations but do not want to continue until I know the best way to continue. I have added categories "Spaceknights (First Generation)", "Spaceknights (Second Generation)", and "Spaceknights (Third Generation)" to help differentiate. Any direction would be greatly appreciated as I am still fairly new at this.
