Pinning Directions to Bottom of Chat?

[srubin]

I am a teacher and often post certain directions to the chat so that late comers know what we are doing. All the other chat submissions bump my directions up the chat. I'd like to be able to pin certain things to the bottom of the chat, so that they stay for new people who enter late.

The "Notes" area in Webex Meetings may be the best location for class session specific instructions.
