I believe this has been addressed before, but here are some easy ways.
Set your home page to VZ mail. Most browsers will start there unless you have it set up to go elsewhere.
Chrome allows you to specify a start page.
My preference is to just keep a VZ mail link on my toolbar, then mail is available with a click anytime I want it. And only if I want it.
I mean really, why would you want to login everytine and deal with advertisements and **bleep** when you just keep outlook up and enjoy your spam in a much happier interface... I haven't received a useful email in three years,
