Features (limitations)

A logged-in user sees a text-input field at the top of the page, which is used to post a message.

A post is limited to 300 characters with no formatting. It uses client-side JavaScript to post and display messages. The most recent 150 posts are displayed in reverse order, youngest to oldest.

JavaScript refreshes the page every 20 seconds. A logged-in user can refresh sooner by hitting the return key or tapping the post button. A user who is not logged-in can refresh sooner by tapping the refresh button.

The client-side JavaScript sends a POST request to the server. The server-side code sends only JSON data to the client-side JavaScript. This applies for the list of messages and for errors.
