A tribune is a type of chatroom. It does not require any external service like IRC or plugins like Java or Flash-based chats, and also works without Javascript (although Javascript greatly enhances the experience).
The module has a notion of threads based on timestamps: typically, a user clicks on the timestamp at the left of the message they want to answer before typing their message. When the message is displayed, hovering the mouse over timestamps highlights the corresponding references and answers, even for old messages that are not displayed anymore.

This module integrates the standards-compliant XStandard WYSIWYG editor by Belus Technology, Inc into Drupal.
XStandard meets very high accessibility requirements. See this blog post at Standards Schmandards for a thorough comparison with other WYSIWYG editors. A feature chart is available at the XStandard website.
The smartlinebreakconverter will selectively apply the line break converter filter (in the core filter module) based on whether it thinks it's necessary.
