      <subheadline>What legal issues should I consider before hosting on SubLite?</subheadline>
      Make sure you have permission from your landlord or owner of your space to sublet. Before you list, you will have to agree that you can legally sublet according to our Terms of Use. 

      Please also ensure all information in your listing is accurate and not misleading. For more guidance, refer to our Terms of Use.

      <subheadline>When should I contact a host?</subheadline>
      As soon as you find a space that interests you. Don’t wait until the last-minute, or it may be gone! 
      <br />
      Legitimate reasons to contact another user are to ask questions about the amenities and to inquire about price. Please contact hosts in good-faith. Spamming is expressly prohibited. For more guidance, refer to our <a href="<?php

../terms.php">Terms of Use</a>.

      <subheadline>What will my listing and profile information be used for?</subheadline>
      We will use this solely to enhance the search functionality of SubLite to make it easier to connect hosts and guests. We require your property’s address so other users can estimate proximity to their workplace. Your exact address will not be disclosed. 
      <br />
      We will not sell your information. You may see targeted advertising from sponsors based solely on non-identifying information such as your university and class year. We will not pass any of your information along to your universities, unless you violate the Terms of Use.

      <subheadline>Where can I leave feedback?</subheadline>
      Whether you like our website or not, we want to hear what you have to say. If you have a funny or horrific summer housing experience, we also want to hear from you. Email us at <a href="mailto: [email protected]">[email protected]</a>.
