I actually do several practical things; I did not mention them in detail since I felt I should not emphasize my own contribution too much. However, since you are asking I will list some:

1. I am supervising the Dhimal dissertation process of my graduate student as a volunteer; it has been an ongoing work for several years, and it is hard and intensive work.

2. I visit the areas where these national minorities live and assist them in their work on illiteracy programs, preparing primers, dictionaries, grammars and language reform in workshops and by giving individual linguistic advice when asked for it.

3. I am actively involved in teacher training, also as a volunteer.

4. I pay all my expenses for travel out of my own pocket, and I also donate funds for those projects.

Now, how do you think you participate in the contribution process?
