To know the rules and regulations regarding submission of articles, If you can see the following two links which will give in detail all the points to be known for submitting an article.
Now you can go ahead and all the best to you.
Yo can learn may things about this site by reading the chapters in help section but for your specific query against article section I will mention a few things from my side.
When you submit an article then three things can happen. First is your article is approved. Second is you are asked to correct it and improve and resubmit. The third is that your article may be rejected as it does not have the minimum quality levels. So, what I will suggest is that go through the existing articles in this site and see their scoring and then compare your article with those bench marks and in that process you yourself will know the worth of your article.
Generally an article will be rejected or approved in 2-3 weeks time. An article can earn anything from Rs 10 to 100 or even more depending upon its language and contents. If your articles are good there is no limit as how many you can submit but it takes time in reviewing them so you have to be patient in that.
Style of writing, grammar, syntax, spelling and good and exhaustive contents are the key elements for a good article.
All the best.
Knowledge is power.
Article content length should be more than 300 word can be considered as good article either here or at blog . Short posting may not get good traffic. Better to avoid short length article. Short length means you can post in forum in form of question or threads.
