There are a couple of ways you can earn on Techulator. If you are good at writing technology based articles, you can post your articles in the section.
Please note that you cannot answer your own questions.
Live....and Let Live!
Each member can both ask a question and post answers to multiple questions asked by other members. But members cannot post any answer to the questions posted by themselves.
It is a good idea to click on the 'unanswered' link in the Ask Expert section. There you will find a list of queries to which nobody has given an answer, probably because of lack of knowledge/expertise. Of course, you can answer an already answered question, but if you merely repeat info already provided in previous answers, it would not really benefit you in terms of points and cash credits.
It is also a good idea to raise a query in the forum that is ideal for general discussion and as such does not require some expert's guidance. Participating in the forum is highly beneficial as it allows you to get to know fellow members, interact with them in an interesting manner and also improve writing & English skills.
The amount would be dependent on the depth, accuracy and originality of the post. Language skill is important too. Though you can refer to the online information available for the question, a direct copy paste will straight away lead to the rejection of your posts.
