Open the Chat window:
Library H3lp webclient https://us.libraryh3lp.com/webclient/#/client
When you first log in, you must choose whether you are covering chat or text or both. I think the default is both.
Go to Chat Tab in this LibGuide.
NOTE 1: If no one is acting as librarian, the chat box will not appear.
NOTE 2: If you are playing Librarian AND Patron, make sure you open each in DIFFERENT browsers.
