CoSketch.com is a free whiteboard program that will allow you to create and share whiteboards with others and embed them into your BLOG. I’m going to use their app to put a whiteboard here. Not all of it appeared to be visible on my preview.
The rest of this was created at their site not using their link that allows you to creat a simplified version.
You can link to your whiteboard by a direct link or you can use a thumbnail picture that will link to the site.
Please give it a try at http://CoSketch.com
One thing I did not show is that you can use google maps as a background to give directions. A nice feature.
Let me know what you think about it.
