reply to #6 on Thread:1229769 Unfortunately, I have no idea how Wikia decides what to include in the map. If I had to guess, I would say: After re-reading Linking to a Fandom community from an off-Fandom community, I did a quick look into the actual difference between "fullurl" and "canonicalurl". It appears to be the extent to which they attempt to resolve the url.
 * 1) pre-existing entries
 * 2) "very large" Wikia communities that have a lot of other communities linking to them
 * 3) common external wikis
 * 4) external wikis about MediaWiki and/or extensions used by Wikia
