Welcome to the forum, vikkipanthi.
The way the forum works is that you ask one question at a time, with a title which includes the word or words you are asking about, such as 'What should we use for a company reference?'
I am amending your title. Please wait for replies before posting your next question.
Please note that sentences should begin with a capital letter and questions should end with a question mark.
