Great idea Jerry,
A lot of users are still waiting for an updated Help File, Tutorial for Hal 6, Read From Text File, Check Email and a few other features.
A Plug-in Guide would be a great addition to both promote Hal and serve the community by allowing for more understanding of what makes Hal tick and for programmers like yourself and others, increased options for writing new routines / plug-ins.
It's a win-win situation...everyone benefits!!
