I am a one man shop and am the only user on my ZOHO account.  When I set up the account initially I put an email address in as my primary email and now I would like to change that.  I've gone into set up and it seems very easy to either add or change my email address but it never sticks.  It's got to be a very simple thing I'm missing but it's got me stumped.  Any help would be appreciated.  Thanks.
