Features:
- One-step connection: press "Connect B24U" in the plugin settings to create a B24U account for your site; the chat appears on the site right after.
- The widget script loads asynchronously and does not slow down your pages; clicks on the chat button made before it has loaded are not lost.
- The widget is printed only on the public site, never in the administrator.
- Updates through the Joomla! Update System.
- The look, texts, greeting and behaviour of the chat are managed in your B24U account.

External service: this plugin connects your site to B24U (https://b24u.com), a hosted service operated by Globerint Pte. Ltd. The plugin is free and GPL; the B24U service has a free trial and paid plans. While the plugin is enabled, visitors' browsers load the widget from i.b24u.com (or i.b24u.ru) and send to B24U what visitors type into the chat together with page and visit analytics.
