#572998 : Only the exceptionally good forum threads and forum responses get cash credits and the others get only points. Anyways, if you earn more points, you are likely to get into the top 20 contributors of a month and get revenue share bonus (a part of the site's revenue given to its best contributors). Coming to referrals, go to 'Invite Friends' of your 'Dashboard' in which you can see a sample mail. Change that mail according to your details (if needed) and send it to your friends. If they join this site through the link in that mail, you will get 10 points and the referral bonus as follows.
Rs. 1 : If the referred member completes registration.
Rs. 10 : If the referred member reaches Silver level.
Rs. 100 : If the referred member reaches Gold level.
Rs. 250 : If the referred member reaches Diamond level.
Rs. 500 : If the referred member reaches Platinum level.
Note that it is not the Rs. 1 + Rs. 10 etc,. when referred member reaches silver level etc,. Instead, it is Rs. 10 etc,. only i.e. Rs. 1 changes to Rs. 10 etc,.
My suggestion to you is to improve your punctuation, sentence framing before starting to post articles. A mistake I observed in all of your forum posts is that the first letter is not a capital letter. ISC is a best site where you can learn and earn. All the best for your ISC future. Hope you will try your best to contribute in ISC.
Let us continue learning.
