We don't have the wikisource: interwiki link prefix
We also don't have the wikiquote: interwiki link prefix. But we have wiktionary: and commons:. See Interwiki map (which really should be Appropedia:Interwiki map). I'd like to have w: in addition to the verbose wikipedia:. I'm trying to make this site more hospitable for Wikimedia Foundation project wiki expatriates. It's a process. See my tasks page. --Teratornis 17:09, 22 February 2011 (PST)
