Tuxpaint -Another whiteboard software, with more of a primary feel, although plenty
powerful. Tuxpaint is an open source "paint" software that has many of the same
qualities that a good whiteboard software needs. It's Free, for Mac, PC or Linux.

Here's a look at the tool bar....very easy training curve,
I'd say about 15 minutes for most users.
