Deleting Old Threads, Posts, or Accounts
When you post, you acknowledge that any submissions you make may be edited, removed, modified, published, transmitted, and displayed by Avian Avenue at any time.
We do not delete old posts or threads. Unless it is in violation of a law, a threat to someone's person, or otherwise harmful, we will usually not edit or delete threads or posts. Old posts are still valuable to our community, as they help us show up in Google search, help teach people who may only read and not post, and give us something to reference if a situation comes up again. Deleting posts ruins the flow of a thread, and deleting threads because they are no longer relevant to you is unfair to the members who donated their time and knowledge to helping you.
Locked threads - If a thread is locked, do not start a new thread to continue the conversation. The thread was locked for a reason.
We do not delete accounts. If you would like your access to the site restricted, our admins can assist in doing this for you.
