Go to the Articles drop down in the Menu above, click on it and then click on Submit Article. It will open a page for you where you need to write the title, summary and the body of the article. You will need to use the basic HTML tags for highlighting headings, making lists and using bold/italics/underline. No need to use "p" or "br" tags as the normal keyboard enter is automatically converted to a line break.
Article should be original, on Technology or Finance related topics, should be a topic that is not too widely covered by other websites and should be of at least 500 words.
