You can embed a realtime chat window into your website, for free, much like the chat window on the side of Suprsede pages. To do so, follow these steps:

  1. Create a new topic for your website
  2. On the newly created topic page, click on the 'Embed this topic chat on your website' link below the chat box. This will take you to a page that gives you the HTML snippet you need to put on your website.
    Here is an example for the programming topic.

You can see an example of the chat embedded into another website here.
