I have added an article from Gilly Salmon - also a bit elderly (2000) but there is a discussion about synchronous discussion. It's in the topic box called emoderating. Does anyone have some articles about using chat? I once wrote a short description of using structures in chat based on something done by a former colleague Stephen Bright. I'll revive that when I locate it. Meantime take a look at what Ms Salmon says. It's always interesting.
I have added some resources into the Forums and Chat section. Facilitating chat is an art form, I reckon.
