You're looking at the gamepedia version correct?
Hi Lunawisp, if you have done many editions the wiki doesn't allow you to add urls, you can do 10 little editions un other pages - selecting this option when you save the work. That should work!
If you still cannot do It after all, send me a pm with the link and where do you like to add It.
Yep, thanks people. I did look at the admin page but it was impossible to leave a message or do anything at all. I saw on the wiki help that it's necessary to do ten edits before you can add an external link. In practice, whether its a bug or intentional, it appears that people without ten edits cannot do anything on any page that contains a link. Since that's nearly every page on a wiki, that pretty much kills off the prospect of any new editors arriving to help out.
I've PM'd Gammea with the link.
