I WANT TO BE A CONTRIBUTOR!!!
I want to contribute Hindi language for English speakers . But I don't know how to contribute ....... can anyone tell me how to contribute??
You should apply in the Incubator itself. See the URL supplied by SaraGalesa.
Note: Hindi already has four contributors - so they might not get back to you.. However, there is no harm in trying, so go for it. Just be prepared for a lack of response.
Suggestion: I see from you profile you are from Coimbatore. I have just read that Telugu is one of the languages spoken there. If you, or someone you know, is fluent in Telugu (or has achieved a very high level) then applying for that course is more likely to result in a response. Currently Telugu has zero contributors. It is currently an English for Teluga speakers course, but I assume that there will be a Teluga for English speakers reverse course, once the first course is complete.
PS: There is no need to shout.
