Wikia is a riddle wrapped in a mystery wrapped in an inappropriate localization to toki pona. I consider myself among the top 50 of toki pona reader/writers and I can't make sense of how to do anything on wikia.
There is a wiki books area for toki pona-- it has avoided deletion so far. Wiki books allows for long format printing, e.g. suitable for sending as a huge doc to a printer or an ebook. Wikia is optimized for a big set of heterogeneous hyper-linked docs that would take a million years for a reader to organize and print out.http://en.wikibooks.org/wiki/Toki_Pona
The 1st author was planning to just copy the jan Pije lessons. I was going to reboot it and do a conlang documentation project in the style of Thomas Payne's "Describing Morphosyntax" outline, which is suitable for a field linguist to describe a language. Unfortunately, I stalled out on that project- laziness and too many questions that just lack an authoritative answer, such as how best to describe toki pona's valence increasing or decreasing operations (i.e. when can a semantically in/transitive verb add/drop an "e"-phrase) A potential improver of the jan Pije lessons will have the same challenge. jan Kipo addresses the challenge by sometimes just making decisions based on intuition and community experience. I am still a bit reluctant to do that because I don't want to take over the design of the language (let the community work out the solutions and express it in the corpus) and if I am going to do that much designing, I will design a brand new language.
There is also a russian wiki books that is just the translated PJ lessons in wiki books format-- so the idea of a wikibook version of the jan Pije lessons are a I don't have the link to to.
