1) Look for rows which have "(archive)" instead of "(archive, gmane)", or that
read "not on Gmane?".
2) Check if those mailing lists are in
http://dir.gmane.org/index.php?prefix=gmane.science.linguistics.wikipedia or
http://dir.gmane.org/index.php?prefix=gmane.org.wikimedia
3) Add links for all the missing ones, following the same format as the others.
