Sometimes, the best idea for what to call a room just hasn't come to you yet. Maybe you start with a working title, and the project becomes something beyond your wildest dreams! You'll want the room title to keep up with that awesomeness.
Here's how to edit the name:
Go to the room you want to rename
Go into your room settings from the drop-down menu on next to the current name of the room
You can also click in the Room Title bar, and type the new name in directly. Hit 'Enter' or click away to save
Write in the new name in the Room Title bar
Make sure to save your changes
Feel like you can get creative, but stay up-to-date and organized at the same time with differentiated room names.
