I was trying to follow the nofollow discussion
(
http://meta.wikimedia.org/wiki/Nofollow#Current_use_on_Wikimedia_projects).
I see it hinges on "external links", and my question about it would be
concerning when an interwiki link to a sister project is deemed
"external". For context, I use many links to Wikisource pages I have
created as references, and was wondering whether the [[:s: ***]]
construction is read as an "external" link.
