text: You can do it for example:\n\nMr. Joe Smith              \n111 West Avenue\nWashington, D.C.  2009\n(put a the left margin)\n\nor\n\nYou can just type the person name and address across you letter, but to be professional you should go down the page, but if it is only names address you can go across, but more than that I would not.  I hope this helps
