I'd like to use Diigo as part of an online course I'm designing. I've been looking for info on the extent to which Diigo is accessible to all, include people who are blind and use screen readers such as JAWS, and to people who have motor impairments and use only a keyboard, not a mouse. Any suggestions? I did send an email inquiry to info at diigo dot com.

When I look on the Diigo Feature Comparison Chart, it indicates that even free accounts get a handful of Screen Capture & Annotations per month. But the Help screen for this feature shows a Capture button in the toolbar to the right of the "Highlight" button. I don't see it. Do free accounts get this? What about educator accounts?
