Meadow Mari  is a Finnic language spoken in Russia. All project-related requirements are fulfilled , including verification that Incubator project  is written in that language.
As they have a major event at July 10th , it would be really good to give them Wikipedia until that date. So, please make the project quickly.
As it is an urgent request and we don't have time to wait 7 days for Board not to say nothing (as Board is not saying anything, usually), I'll send an email to Michael and Brion to make consultations about the issue and to create the project ASAP.
The Wikimedia Foundation  has received a request for a new Wikipedia in the Acehnese language. A group of volunteers have worked hard to provide enough content for it to start. In the past we used to trust the language to be what it was said to be, but sadly this trust was abused. It is for this reason that I ask your cooperation.
We have been informed that you are able to give us an objective assessment of the language used. We would like you to answer two questions.
Can you confirm that the texts  are written in the Acehnese language,
the definition of what we expect it to be is provided by Ethnologue 
Can you tell us why you are in a position to affirm that it is Acehnese?
Thank you, language committee Wikimedia Foundation
Here is the confirmation for the Mirandese Wikipedia.

After a cautious analazis of all the entries on the Mirandese Wikipedia and I can attest that it is written in Mirandese, in acordance with the Convenção Ortográfica da Língua Mirandesa (Mirandese Orthographic Convention).
I can attest that because I am the President of the ALM - Associação de Língua Mirandesa (Mirandese Language Association) and a teacher in Universidade de Lisboa, as well as a Mirandese teacher. The Mirandese is an official language of Portugal, recognized by law.
Thereby, I think that the Mirandese Wikipedia has the conditions to be accepted.
Vi com muita atenção todos os textos da Biquipédia Mirandesa e posso atestar que está escrita em língua mirandesa, de acordo e respeitando a Convenção Ortográfica da Língua Mirandesa.
Posso atestar esse facto porque sou Presidente da ALM - Associação de Língua Mirandesa e professor na Universidade de Lisboa, incluindo professor de Língua Mirandesa. O mirandês é uma língua oficial de Portugal, além do Português, reconhecida por lei.
Assim, penso estarem reunidas todas as condições para que a Biquipédia Mirandesa seja publicamente apresentada.
Generally, I support such project requests: If it is about a large language group which doesn't have good Internet access (like in Sorani case), it will be changed in the future. If it is about a sustainable smaller group (like in Mari case), the level of involvement won't be much higher, but Wikipedia will have an important place in preserving their language and culture. (I am just against wasting efforts of very small language groups on Wikipedia.)
