This is Chat2, which is an update to original Chat Room published on CSS-Tricks. In some ways, the technology is the same. We employ PHP to talk to the server, jQuery to keep the chat rolling, and the chats themselves will be stored in .txt files just like the first version.

There are some new features in Chat2. Usernames are now unique to users currently chatting. You can see a “currently chatting” user list. And there are multiple rooms for chatting available now.
