While the objective behind the suggestion is prudential and well appreciated, the communication of grants from individual community and following chain of responses and replies will flood the email box. Being from a particular language or working on particular project, A volunteer might not be interest in detailed of the project. So I believe, inclusion of grant proposal may not be included in India list. It may be kept at community level mailing list only.
However, In order to keep the Indic communities groups abreast, a fortnightly or a monthly email can be sent on Indic List, along with link. Interested person can follow the link to get more information.
