Hi John,
appreciate your initiative and welcome it!
* As for languages- not so sure about UN-languages but some African languages should be in it - the 2 most relevant presently being Afrikaans and Kiswahili (statistically strong are also Malegache and Yoruba, lets see if they can participate?)
If you add more languages the table gets difficult to handle, too wide. Reorganize it any way.
I will add some for sure in swwiki.
Cheers Kipala
