The "External Links" subsection title intent is ambiguous because this whole article is about Links & Linking.
So this subsection has Generic Mediawiki References on embedding Links... not guidelines for adding external links to Gramps wiki pages. (The other possibility was that the table above was to be segmented into 2 tables: 1 for internal link examples, the other table for external.
What do you think about re-labeling the subsection?
