Many people have been asking how to contribute to GO. So, let me brief..
As a GATE aspirant the best way you can contribute is by learning the concepts correctly, getting a good rank and giving a feedback. There is nothing more expected here. Those who knows to explain well can explain and help others. But this should never be done at the expense of one's own preparation. If one explains, he understands more. But no need to do this if you feel otherwise as repeated explanation also won't add value to your knowledge. After joining IISc/IIT or any good college, whenever you find anything you can contribute you can give back to newcomers here like admission stats, announcing research opportunities etc. I do not expect any Masters person from good colleges to contribute here as it'll affect their studies and I know how busy life there is. Aim of GO is to improve the quality of education and you can help it -- but first help must be for self.
Now, if you have enough time and want to contribute you can do it. What to contribute? If you have been here and know how things work here, you should know. I'll list 3 contributions to GO not directly related to the contents, which became quite popular
- Kathleen added previous year GATE questions here
- Pragy Aggarwal made the GATE rank predictor - this is open source
- Arindam Sarkar made the GO Exam plugin
- Bikram Ballav made the Exams
The above 4 were not asked by me and they did this on their own. So, anyone can do like this. There is no need of having a cool idea - because in the end implementation matters. If you see there is nothing innovative in GO- Q/A sites were already existing and even in GATE domain. If you do not want to implement anything, fine, you need not. On the other hand if you have an idea and want to try it no one will stop you. Just discussing any idea without wanting to implement is useless as no coders are here to do it.
Many people have asked for contributing to the GATE CSE book. I guess you would have seen the Digital Logic book last time and I plan to make other subjects on similar lines. It won't be a book of "notes". But should act like a guide for following text books. Many people have contributed to it and now whatever I want to do on it I plan to do it myself. But if you have anything specific you want to add -- say some nice programs under relevant chapters -- then you are welcome to do so.
And if you are expecting anything in return for the contribution you need not contribute. Also plagiarism is strictly prohibited here as that is the major reason for poor education quality among graduates. So, if you copy from somewhere and answer here, you risk either being penalized or from being banned. There is no reason to answer here for getting points alone -- as there is no major advantage for it. Answer here only if you know it and you want to contribute what you know. I mean as a student answer questions only if you have a small teacher in you.
If anyone is interested in making an addon for GO it is pretty easy as GO is using the open source Q2A platform. You can get more details here.
