Welcome back. You can definitely find out the details about different sections in the help menu but there are some basic things that I can share here.
This site has a moto - Learn to earn, Earn to learn! So here you learn many things especially how to write creatively and how to present your ideas in best possible ways.
Time to time, there are contests which give all the members an ample opportunity to showcase their talents. There is a very healthy competitive environment and once you deeply involve yourself in these endeavours you will enjoy participating in the contests more and more.
The forum section is the most vibrant one where everyday you will find many new issues out of which you can select your choice to respond or you can start your own thread and see how people respond to it. In this section you gather points and occasionally some cash credits depending upon your outstanding contributions.
If you are keen in answering questions asked by others the Ask Expert section is for you where questions on many subjects are asked and other members answer it. These answers, when approved, bag cash credits in addition to the points. You can even ask your question also here.
You can submit articles in the Article section and depending upon the quality of your article you will be renumerated points and cash credits from 20 to 100 or even more. Try to write the article in a comprehensive and full of content mode otherwise if it does not conform to a basic quality, it may be rejected. So go through some of the articles, read them and have a feel of them.
You can post the jobs in job section by writing them in your language. This requires a detailed posting about the jobs and any thing missing will make you score less here. You will get points and cash credits both here ranging from 3/4to 10/15 and may be more.
Another section is Information update where you can write about places, schools, colleges etc and earn revenue and points ranging from as little as 3/5 to even 70/80 and sometimes more depending upon the coverage and quality.
Time to time, to encourage the good contributors, ISC announces awards like Thread of the Week, Star of the Month, Wizard and Super Contributors in a month, Star of the year etc which renumerate the winning members cash credits anything from 40 to 1000.
This is basically an educational site and has more thrust on educational material. You can post exam question papers, model question papers, articles on educational entrance tests etc and earn commensurate revenue.
So there are many opportunities here for creative writing and you can contribute and enhance your creative skills and also earn some pocket money for yourself.
So go ahead and all the best.
Knowledge is power.
