Hallo!
I am going through https://meta.wikimedia.org/wiki/Category:Open_requests_for_new_languages , project by project, letter by letter, up to ten requests per email, one email per day.
I am now working on Wikipedia, and today I'm handling the letter T.
I took the liberty to delete https://meta.wikimedia.org/wiki/Requests_for_new_languages/Wikipedia_Taiwan_... . It was posted by a user who didn't do much else and had no substantial content or discussion. I already tried contacting the user and got no response.
== Toki Pona == Request: https://meta.wikimedia.org/wiki/Requests_for_new_languages/Wikipedia_Toki_Po... Code: tok My take: Eligible. It appears to be seriously active online for all kinds of purposes, and has book publishing. I don't know for how long will this community remain active, but I cannot think of any reasons to block it according to the current policy.
== Triqui == Request: https://meta.wikimedia.org/wiki/Requests_for_new_languages/Wikipedia_Triqui Code: trs My take: Eligible. Very little content in the Incubator, but the request appears to have been created in good faith, and the creator is still active. I pinged them on the talk page.
== Tunica == Request: https://meta.wikimedia.org/wiki/Requests_for_new_languages/Wikipedia_Tunica Code: tun My take: Eligible, with nearly identical explanation to Triqui. This one is more of a revitalization project and not a totally naturally living language, but it appears to be serious enough.
== Tunisian == Request: https://meta.wikimedia.org/wiki/Requests_for_new_languages/Wikipedia_Tunisia... Code: aeb My take: Waiting. There is some opposition in the discussion section, but it's a common theme of "it's not a separate language, but only a dialect". My impression from reading about that language is that it is becoming a stable, distinct, standardized written language, comparably to the related (but also distinct), Moroccan Arabic (ary). I am not suggesting a full "eligible" status at the moment because the request's creator appears to be engaged in a serious, academic attempt to stabilize an orthography. It waited for a few years, and the request creator has also been active in various other Wikimedia activities, so it can wait some time more until the writing system question gets clear.
