Zamzar

I'll admit I don't really understand all the uses for Zamzar.  But the blog says you can convert to ereader format, which would be nifty if someone needed to change a personal document into that format.  Sorry, rambling, trying to get my head around this tool.  I practiced converting the AASL Standards for the 21st Century Learner booklet from pdf to doc.  This conversion allows me to edit the brochure--not that I have any suggestions to make!  But I can imagine a scenario when I might want to work with a pdf and Zamzar makes it possible.  Also, from the Zamzar blog, there seem to be conversions that would be useful for ipad users.  I'll try to remember this resource when I'm stuck in the wrong format....
