What is a one-sentence summary of the following article?
You will need to send your letter of recommendation to the admissions office at a college. If you're a student, you often have to provide your teacher with an addressed envelope when requesting a letter of recommendation, so make sure you know the proper address.  If you are a student, the address should be specified somewhere in the application instructions. You can also find the address of a college's admissions office online. However, you should call the office to double check this is the proper place to send application materials. If you are a teacher, your student should be able to provide you with this information. If your student cannot provide the information, you can also check online and call the admissions office. In the middle of the envelope, you should print the address of the administration office. Make sure to print clearly so the letter is delivered to the proper place. If you have sloppy handwriting, consider making a trip to a print shop to type and print out addressed envelopes.  The first line of the address should say something like, "Office of Admissions" or "Admissions Office." The second line should include which university the letter is being sent to, like "Michigan Technological University." The third line should include the address of the admissions office. For example, "123 Maddison Street." The last line should include the city, state, and zip code. For example, "Houghton, Michigan 49931." You can also use your own computer or a typewriter to print address labels for an envelope. This may be a good idea if you have sloppy handwriting. The return address is the address of the person writing the letter. If you're providing your teacher with an addressed envelope, you may need to ask for his or her personal address. However, it's usually safe to simply use your school's address. If you're filling out an application for a student, simply put your home address.  The first line should just be your name, or the name of your teacher. For example, "Elizabeth Hart." The second line should include your address, or your teacher's address. For example, "262 Paulina Street." The last line should include the city, state, and zip code. For example, "Chicago, Illinois 60657." In order to assure the letter smoothly gets to the right place, include details on what the recommendation is for in the lower lefthand corner. Admissions offices get letters regarding things like scholarships in addition to applications for admission, so there may be multiple branches of an admissions office.  In the lower left hand corner, write "Re" followed by a colon. From there, include some specific information about what the letter is regarding. You can write something like, "Letter of Reference for Jane Meyers, fall admission." If you're applying to something like early admission, it may be a good idea to include that information as well. All letters require proper postage if you want them to be mailed. You can buy stamps at a post office, as well as many grocery stores and drug stores. Place a stamp in the upper righthand corner of your letter. If an envelope contains materials beside a letter, you may need two stamps. If you're unsure of postage, go to a post office and ask. You want to make sure your letter is mailed successfully.

Summary:
Find the address you need. Print the address clearly on the envelope. Put the return address in the upper lefthand corner. Include specific details on the envelope. Make sure to include a stamp.
