It is true that you can go to help topics and get all the information. Anyway, for the benefit of new members, I will just briefly tell the salient features.
There are some sections like Jobs, Articles, Ask Expert, My India, Resource response etc where you are given points as well as cc.
In the article section, you can get points and cc from 20 to 100 or more depending upon your quality.
In the Ask expert section, one can get points and cc from 2 to 6 or more depending upon coverage and quality.
In the job section, you can get around 5 to 10 points and cc.
In My India section depending upon your entry, you can collect somewhere in the range 10 to 60 points and cc or maybe more if you have covered all the aspects.
In resource response (comments to the article) one can get around 2 to 6 points and cc though good comments can fetch you even more.
There are other sections like the forum in which there is no quick cc but points will be allocated up to a maximum of 5 for each thread or response. In rare cases where the matter is unique, some cc can be given generally in the range of 3 to 10.
Other than this there are contests announced from time to time where you can participate and earn the prizes ranging from cc 50 to 200.
Further, if your contributions are plenty as well as of good quality you can automatically qualify for weekly awards 40 to 60 points and cc and also monthly awards ranging from 250 to 500 cc. So there are many contesters but there are many opportunities also.
Those who are contributing in large scale and if they fall in top 20 in a month, they are entitled to revenue share bonus in that particular month which can range from 150 cc to 1000 or even more depending upon the total contribution.
So go ahead and contribute in the sections of your choice. All the best.
