Chat Participation

I know this is a struggle for all.  I have noticed that once one or two participants start responding in chat, the others often feel more encouraged.  I would love to have a "fake" person or really a second me to add to chat as another participant rather than the facilitator.  I think this would encourage others to respond as well.  I find that once chat is started by one participant or two, often others feel encouraged to chat.

I hope this makes sense - I just saying is there a way to pretend to be a participant instead of the facilitator to chat?
