From Rosetta Code

Biferno and Bifernod are currently showing up in main rather than as language pages. --Rdm 19:31, 19 September 2010 (UTC)

I'm not sure what that means. Bifernod is in the main namespace which seems to be how we've done implementations (I use QuickBasic/BASIC as an example for that), and Biferno has a category page and a redirect from the main namespace. They seem to be set up correctly. --Mwn3d 22:09, 19 September 2010 (UTC)
