I notice that [eng] is listed as an L2 for To'abaita, but not Pijin [pis]. This must be an oversight as Pijin is widely spoken in the To'abaita area as an L2, or at least it was when I lived there 30 years ago.
Further, I notice on the Pijin page, that only 12 languages of the SI are listed as using [pis] as an L2, but I know the number is much higher than 12.
We will list Pijin [pis] as an L2 for To'abaita [mlu]. We will contact a knowledgeable person in the Solomon Islands for feedback on other SI languages that have Pisin as L2.
