Hi, all.
I'm aokomoriuta, who was (is?) one of the Phase III Ambassodor team on jawiki. Thank you for notifying about this list. Now I am subscribing this and will share information with jawiki community.
And, can I inform other people about this "wikitech-ambassadors" list?
I mean other is sysop private ML, WikiJA-L public ML, or Noticeboard on jawiki; or not only wikipedians but anyone interested in our topic.
