Have any of you heard of this before? The English on the site is a little wonky, which makes me suspect they aren't native speakers, but I haven't read it cover-to-cover yet, so I might be missing something there. I'm also skeptical of the fact that they're using digraphs to refer to languages (e.g. BM for Bambara/Bamanankan), rather than trigraphs (e.g. BAM for Bambara under ISO639-3).
Anyway, it seems like a neat idea!
