tpi.wikipedia.org - Tok Pisin
One of the official languages of Papua New Guinea. Some pages should be
moved from temporary work at
bi.wikipedia.org over here.
io.wikipedia.org - Ido
Ido is a cousin of Esperanto, rarely seen but of some historical
interest.
tp.wikipedia.org - Toki Pona
Toki Pona is a more recent conlang, but with a relatively active and
enthusiastic user base. ('tp' is not assigned as a 2-letter code, and
ISO isn't assigning any more 2-letter codes. Rather than fight about
what to call it, I figured 'tp' will do.)
