A “handle” is a term that CellarTracker, our data provider/partner, sometimes uses instead of “username”.

Here’s a step-by-step guide to setting up an account:

First, let’s be sure we’re starting from scratch. In Cor.kz, tap on the “Settings” icon in the lower right. Scroll to the bottom and tap on “Clear all Settings”.
Cor.kz will restart and it will be as if you started Cor.kz for the first time.
Now tap on “Settings” again.
Under “CellarTracker” tap on “(Not Configured)”.
Now tap on “Set up free account” or “Use Existing Account” if you are already a CellarTracker user.
Enter a username, password, then your Full Name and email address in the appropriate fields.
Now tap on “Done” (and again on "Save") in the upper right corner of the screen.
You should see a message that tells you “Account Created”.

That’s it! Good luck!
