I'm a new user - don't assume I know anything.

In the online Help, everything I try to learn about contacts - adding,
finding, etc., the Help always begins with "In contacts,..."

I've tried for 5 months now to figure out how in the world you get "In
Contacts"

There is no menu item or button anywhere that says "Contacts".

Every time I send a message I look at a sticky note and type the email
address in, because I cannot figure out how to get "In Contacts".

Can someone please Help!!!
