I would like to use Evernote ask my "one stop" location to make notes at work. I need to be able to create a stack within a stack...for example Company Name (notebook stack 1) > Committee 1 (notebook stack 2) > meeting 1 (note) > meeting 2 (note) > meeting 3 (note) etc.... >Committee 2 (notebook stack 3) > meeting 1 > meeting 2 etc... Is this possible? I have been trying and it doesnt seem to work. Thanks.
