Dear Violetta: I don't know exactly how the chat page works but I have discovered the paging function, on our course WebBoard chat page. The page function shows us who's online for this course while we're on. We can send a page to any of the people who are online with us in this course and the page pops up on the screen. The page function works sort of like instant messaging. I've written more to you in student discussions. Check my message. Well, hope you receive a response to your question here, from the instructor soon.
Take Care, Shaunasi
