Vanilla is W3C standards compliant forum software with valid XHTML and CSS. It includes a templating system which allows Vanilla to be easily integrated into an existing site layout.
Vanilla’s most ground-breaking feature is the framework upon which it is built: the Lussumo Framework.
This framework allows developers to create and add new extensions to the core software.
The basic installation of Vanilla comes with very few features, but there is an add-on site at http://lussumo.com/addons where you can get all of the latest new extensions.
Here are some of the most popular extensions for Vanilla:
RSS and Atom feeds
Whispers, for private conversations.
Intelligent search and search bookmarking system, for users to bookmark their most used searches.
Search-engine friendly URLs
Forum announcements
Animations using JavaScript
