well if you have left it on your screen and not close it you can write in there and when they come back on line it will be there for them to see.
No problem. I too had the same dilemma of trying to reopen a chat window that I accidentally closed. Open the main chat box window. The box at the bottom right that says "Chat (35)" or whatever number might be there. At the very bottom of the list is a search field. Just type in any part of the user name you remember and the search results will come up. Click on the name and the old chat will return. Also, if you click the option gear in the top right of the mini chat window, you can "Pop Out Chat". A new javascript window opens that has more of the chat history than what the mini window can show.
What I would like is a better experience with chat on my mobile. The popup chat isn't available on the main page and on the Messenger page it doesn't scale to the mobile's screen size.
