Additional version of Nynorsk (nn)?

The fact that we have articles in Høgnorsk was mainly pointed out to show that it is relevant for the Nynorsk Wikipedia. It is at present rare to see new articles written in Høgnorsk; instead many of those who write Høgnorsk tend to write articles in the "real" namespace (and thus in "official" Nynorsk), rather than articles in parallel. So, even though you will see Høgnorsk written from time to time in debates and in recent changes, there is a low influx of articles. The number of Høgnorsk articles appears to me to be 42 (created by various authors); which is an insignificant number compared to the more than 63 000 articles in Nynorsk. Yet compared to what I wrote about Høgnorsk being relatively frequently used in debates etc.; I wouldn't give this exact number too much weight (focusing on the usage on the wiki as a whole; rather than just in the articles). The external Høgnorsk wiki does in comparison appear to have 135 articles, being three years younger.

You ask about context. The Høgnorsk standard is used just as any modern written standard is; it makes no real sense to talk about context. Høgnorsk is not a modern revival; the term was coined in 1922, and the first organisation working for Høgnorsk was initiated in 1965 (or so it appears to me); whereas the new version of Nynorsk that the movement was "created in response to" was introduced in 1938. The changes were, as hinted to previously, made in order to make Nynorsk more similar to Bokmål - as opposed to reflecting changes in spoken language etc. (which is sort of hard for Nynorsk, as it builds on the Norwegian dialects more or less as a whole).

To sum up: the language is not used for fun (it might be accurate to say that, to some extent, it coincides with the written Nynorsk standard from 1917), nor is it a revival of something that is dead (despite the connotations the year 1917 may give, Høgnorsk is for example often closer to my own dialect than what the "modern" official standards are - and people speaking different dialects would agree with me but with different examples). And indeed as I hinted to earlier, there are a few different organisations working for Høgnorsk - as opposed to it being used only by a few non-associated individuals.

Do I think people will use a Høgnorsk localisation? Yes, absolutely; otherwise I would not bother with this. I bet people who otherwise do not have anything to do with Høgnorsk could want to try out what the user interface looks like, in Høgnorsk, out of pure curiosity; and maybe even stick with it - for example.

What I am looking for is a wiki that is in Høgnorsk. Thanks,

If I understand you correctly, I have already provided that: Mållekken.
