I'm not a member of the Langcom, but I've been subscribed to this mailing list for quite a while now. Since my primary field of interest is constructed languages, let me tell you why I am inclined to support this request. Mind, I am in no way involved with LFN itself.
My point of view is that there is only one criterion that should really matter for allowing a project to exist, namely the question: is it sustainable?
At present, we have Wikipedias in seven constructed languages: Esperanto, Volapük, Ido, Interlingua, Interlingue (Occidental), Novial and Lojban. Of these, only Esperanto has native speakers, albeit an extremely low number compared to virtually all ethnic languages with a Wikipedia. Yet, the project is thriving. With >236,000 articles it is #32 on the list, which is more than Wikipedias in for example Greek, Danish, Bulgarian and Hindi. Ido and Interlingua (#98 and #109) are doing fine as well, in spite of the fact that both languages have no native speakers and less than a thousand users. The number of Volapük users is not more than a few dozens, but the "Vükiped" is doing reasonably well anyway. Even Interlingue seems to manage somehow, although its number of users (I always avoid the word "speakers" in the case of constructed languages) is probably less than ten.
The only project that IMO has become a failure is Novial. Currently it has 1,644 articles. About 50 of them have some real critical mass, perhaps another 200 are more than just one or two lines of text, tables and infoboxes. After its foundation it had a few enthusiastic, active users, but they all seem to have vanished a long time ago. Since 2011 practically nothing has been happening over there. New articles still appear every once in a while, but most of these are the work of people who don't even know the language and just copy info from other articles, giving articles whose sole content is: "George Clooney is an American actor".
Wikipedia projects in three other constructed languages have been closed in the past, for different reasons: Siberian because it turned out a hoax, Toki Poni because it is a minimalistic language with just ±120 words, Klingon because it is a work of fiction with a vocabulary too small for creating a viable project in it. For the same reason, Quenya and Sindarin are not suitable either.
Anyway, compare all this to Wikipedias in African languages, for example Oromo: a major language with 60 million speakers, but only 726 articles, most of which are oneliners like "Germany is a country in Europe" or even empty. Where's the educational value in that?
Speaking about educational value, I think this boils down to two things: communicating valuable content, and working with the language itself.
When it comes to perusing Wikipedia because one is looking for info, a vast majority of the projects we have are quite unnecessary. Speakers of Bavarian, Luxemburgish, Rhaeto-Romance, Belarusian, Bashkir or Pennsylvania German won't be looking for information in their native language, they will look for info where they can find it, and in a language they speak fluently, i.e. in German, Russian, English etc. Wikipedias in languages like that serve an entirely different purpose: they offer a platform for generating content in a particular language, for practicing it, developing it, showcasing it. In other words, these projects are there for the sake of the language itself rather than the information presented in it.
And in this respect, numbers of native speakers are completely irrelevant. Latin has no native speakers, but its Wikipedia is still a success. What really matters, in other words, is whether there are people willing to write in it and read in it.
LFN is of more recent date than the other auxlang projects, but remarkably vivid nonetheless. I don't know if it really has 100 active users; numbers like that are notoriously difficult to verify, and the only persons who really have an idea about these figures are the same ones who have a vested interest in exaggerating them. But it is clear that there is a large number of people involved in it anyway, enough to generate quite some content. Of course, nobody knows what will happen when the author of the languages stops being involved with the language for whatever reason: it might go down the same road as Novial, but that would be a worst case scenario. In any case, the LFN wiki at Wikia (
http://lfn.wikia.com/wiki/Paje_xef) has 3,774 pages at present, and keeps growing. Quite a lot of these pages are substantial articles, some of them having even more content than their equivalents in the major European languages. Obviously, not all pages could be moved to a Wikipedia in LFN, as they also contain translations of poetry and prose, but still, even at the very start this Wikipedia would be at a higher level than those in Interlingue, Novial, Volapük and Lojban. Not only in terms of numbers, but also in terms of substance and quality. So why not give it a chance?
