Just referred back to this thread--I am amazed at all of the resources being used by VAs--again, thanks for sharing all of this wonderful and useful info.
So far my favorites are:

Microsoft Office for Small Businesses is a great resource also.
I just realized I don't have five just yet! Need to get busy.
