Not that I have anything at all about a Wikipedia in murcian, or quenya for that matter, but:
murcian (a language spoken by more than 300.000 persons) in the south-east of Spain, between the castilian and catalan)
The ethnologue (http://www.ethnologue.com/) has no entry for "murcian" (not even for "panocho", which I assume you're referring to), neither does the English Wikipedia. There *is* a reference in the Language Museum (http://www.language-museum.com/m/murcian-panocho.htm), however.
I must say, I would dispute the claim about the 300,000 people, as not a single murcian I know ever talked that language, or even *about* that language, to me. I'd be most linguistics experts would not classify "murcian" as a language, but as local variant of Spanish (but I assume this is gonna cause some friction :)
But anyway, the point is moot, I'm not gonna say to you whether you should or shouldn't start a Murcian Wikipedia, of course (not that I would have the slightest authority, I'm just a lurker here).
The problem is this one:
two weeks ago.I have already got the support of more than 6 persons. I am > sure more people will be interested.
With a speaker base of 300K, most of them no interested at all in the Wikipedia, do you really thing it is going to fly someday? I'd say the real "collaborator base" is way too small to make a possible Murcian Wikipedia successful. Or are you talking about a Wikipedia restricted to all things murcian? (which would, perhaps, be more logical and far, far easier)
Just curious, no hostility here,
