Before you begin to ask questions and start answering them, I would recommend that you read questions and answers of renowned members. God through them, view them critically, and you will learn to ask and answer questions.

Very simple. You just ask qns what you want to know.
If you know the answer for a given question pl answer in your style.
Pl follow guidelines.

Drink fresh 'tadi' for asking good question.
Take bath for answering well.
Simple.

Be clear in your questions. Check it to see whether the reader can understand the point on which you seek some information. While answering any question answer it to the point. The tone in which you are either asking or answering is not heard here. So, put necessary punctuation marks or universally understood marks. A good answer should be to the point. Such answers may get categorised as best answers by the questioners. Percentage of your best answers is also shown by Rediff on your "My page-My Stuff-Q&A". That is indicative of how well you are answering.

Its all in Ur brain. Read first and reply with sense, wit and meaning or intent.

Well, there's nothing like good or bad qns....., u can always ask qns related to personal or general problems, some interesting qns on any topic.....e.g, health, hygiene, beauty, education, relationship, science, politics, economics, history, geography and so on..........

the only thing that u shd take care is that qns shd be relevant and shd be asked in a polite manner.....and not in an offending way....as that goes against QnA guideline......

as for answering qns....u can answer the qns on the topics u are well-conversant in and answer them in a systematic way, making ur concepts clear.....; try to find out what exactly is asked in a qn.......and try to be relevant and pertinent........; never try to beat abt the bush and make things confusing...!! i have noticed, a few people answer qns in a most irrelevant way, their answers, having no connection with the qns they are answering........

Just be yourself

Chosse your questions.Post such questions which may seem interesting to most of the people.Never ask personal questions.Also be choosy in answering.Answer only questions which interest you and whose relevant answers you know.
