Thread stamps help indicate different actions made to a thread such as if you are watching the thread or if an Admin has replied to the thread.
The little binoculars mean that you are currently watching the thread. This means that you will be alerted to new replies made to the thread. When you post or reply to a thread, you have the option of having it automatically be watched. To turn this option off, visit your Hypixel Forums settings. If you want to watch a thread but do not want to reply to a thread, you can click "Watch Thread" in the top right hand corner of any post.
If you want to stop watching a thread, you will see "Unwatch Thread" available in the top right hand corner instead. This will stop sending you alerts about the thread.
A pinned (or stickied) thread is a thread that will stay at the top of its forums section forever until unpinned. Pinned threads have a red/orange fade on them in the thread listings and have a little tack on them.
Pinned threads will typically be important news or guides that relate to the forums section they are in.
A lock on a thread means that nobody can reply to the thread any longer. Threads can be locked for many different reasons including rule breaking or the question of the thread being answered. If a thread is locked, it can still be viewed but can no longer be replied to. If your thread is locked, it was locked for a reason. You do not need to make a new thread.
A Hypixel H icon means that an Administrator has replied to the thread.
A redirect means that the thread has been moved and you can find it in a different Hypixel Forums section now. You can have a thread moved by asking a staff member or clicking "Report" and saying "Wrong section, please move to X". Moving a thread does not always mean that it will leave a redirection.
The thread that has been redirected will show no replies, views, or recent commentator names in that section. Since it has been moved, all replies and views will be seen in the new section.
