If you create an account in the Cadent Cloud with the iPhone version of Cadent wineCellar, you can "attach" the desktop version to that account by doing the following

• Choose "Create Account" under the File menu of desktop wineCellar.
  
• When the create account dialog comes up, enter the username and password the same as the accont you created with the iPhone version. You will have to repeat the password in the "Repeat" field.

Clicking "ok" will effectively attach your desktop version to the existing account thereby increasing the limit to the number of wines you can sync from 200 to 500.
