I’ve been getting up to speed on ToolBook, one of the older authoring tools. It’s not too bad though a bit clunky. It has some standard issues – what you see isn’t really what you get, bullet points are pointedly problematic. In publishes to HTML which could be a plus though. One thing I have found is that there is quite a lot of documentation out there and some good resources:
Toolbook.org – useful blog with ‘how to’ and links
Toolbookdeveloper.com – this has free and paid for widgets and add ons for toolbook
ToolBookConsulting.com – the blog has lots of tips and links to downloadable widgets and fixes
Let me know if you know of any other sites I should be aware of.
