You might have noticed the little icon in the top-left of MoneyWiz interface that looks like a person when you're signed out from MoneyWiz Cloud and like MoneyWiz avatar when signed in.
You can personalize this avatar if you want. To do this, simply sign up for an account at Gravatar service. You'll need to link the e-mail you use for MoneyWiz Cloud with an image of your choice. MoneyWiz will recognize this change and start showing your avatar in MoneyWiz.
Please note that you don't need to create your Gravatar account with your MoneyWiz Cloud e-mail in order for this to work. Once you have a Gravatar account, you can add other e-mail addresses to your account (e.g. you create an account using [email protected] but your MoneyWiz Cloud e-mail is actually [email protected] - you can create your Gravatar account using the first e-mail and add the second e-mail later).
