With all the talk about user-generated content out on the web, there's been less interest in what people are talking about as they browse around. Trailfire may create more discussion about such material, as it allows users to leave electronic notes on various webpages for other visitors. It's quite a bit of fun, and visitors can also view different "guides" posted by other users to the Trailfire homepage. A basic tutorial will help new users get started, and there are also a number of support forums here as well. This version of Trailfire is compatible with all operating systems running Windows XP or Vista. This archived version of the software is available for download from CNet.
