All the sections are assailable in TSR is good. But, my point of view resource(Articles) section is good due to the following reasons.
The article section in TSR gives more money and points to the TSR members.We can post any articles in this section which is related to Tamil Nadu. There are many resource portions are available in this section.
By posting the articles with various topics, we can improve our knowledge. The article posting is good habit which improves our general knowledge. This will help us to attend the competitive exam like TNPSC, UPSC,CIVIL Services.
It also gives many articles of others which helps us to know about various things and objects, places in Tamil nadu. So, the article section is good than others in TSR.
