You can change the description at any time. Keep your description short and write it so that it helps others decide whether to request membership and whether to set up notifications to keep tabs on what’s being discussed in the room. When you create your chat room, add a description of the purpose. Changing a room name can create confusion for users who’ve set up notifications or added your room as a Favorite.
It’s a good idea to find an appropriate name to start with and then stick with it. Note: If you decide to change the room name later, the new name will be displayed for you and the room’s members and followers going forward.
