Interwiki Wiki for wiki books
Concerning the shorthand link address for Wikibooks using "b:" didn't work. It is putting the text as red. It is saving the "b:" as B capital, however using "wikibooks:" works fine. Please I would like to know why is this so.
Hoping to hear from you soon.
Yes, wikibooks: is the interwiki link for Wikibooks.
