Hi Maury,
it would be nice to have a free dictionary English - Sonsorolese on the internet ánd a review of the grammar... I am a Belgian and I'd like to learn Sonsorolese. Maybe some people of http://cas.gmu.edu/~tobi/ can help you. They are specialized in Tobian, but maybe, there are some contributors who know some Sonsorolese words and grammar rules.
Greets, Deadinimara (= Nauruan for "pig")
PS I prefer not to give an e-mail adress. You can post a message on http://na.wikipedia.org/wiki/user:belgian_man . That is my page on the Nauruan Wikipedia. You can also see in which languages I'm good there.
