At the beginning of the chapter we saw why one can face problems when communicating with other people in a dynamic way over the Internet. We saw what the solutions for these problems are and how AJAX chat solutions can bring something new, useful, and ergonomic.

Simple command lines (joining/leaving a chat room, switching between chat room)
