Chat gets busy fast. Pinning is how you stop the important stuff from sinking to the bottom. The slightly confusing part is that "pin" means two different things here, so let us split them up.
Pinning a conversation (just for you)
This keeps a chat at the top of your chat list, above your other conversations. There are two ways to do it:
- From your chat list: tap the 3-dot menu on the right side of the chat's row and choose Pin chat.
- From inside a DM: tap the 3-dot menu at the top of the open chat and choose Pin chat.
A small pin icon then shows next to that chat's name. To undo it, open the same menu and choose Unpin chat. Pin a few chats and they sort themselves by who messaged most recently, so your favourites stay together at the top.
{{callout:blue:Info}} Pinning a conversation is private to you. The other person is not told, and their chat list does not change. Global Chat always stays at the very top anyway, so there is nothing to pin there.
Pinning a message (for everyone in the chat)
This one is public. It puts a single message in a banner at the top of the conversation, showing who sent it and a preview of the text, so nobody has to scroll to find it.
To pin one, open the message's menu (right-click on desktop, or press and hold on your phone) and tap Pin. To remove it, tap Unpin in that same menu, or tap the X on the banner.
- In a DM, either person can pin or unpin.
- In Global Chat, only Staff, Moderators and Admins can pin, so a random "first!" is not going to take over the banner.
- A message that has been deleted cannot be pinned.
{{callout:gold:Lightbulb}} A chat has room for one pinned message at a time. Pinning a new one replaces the old one, so if your plan for Saturday suddenly vanished from the banner, someone pinned something else.
Which one do I need?
If you want to find a chat quickly, pin the conversation. If you want everyone in the chat to see something, pin the message. Both are handy for a plan, a meeting spot or a "do not forget this" reminder.
