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 SYNCbits and like MoneyWiz avatar when signed in:
You can personalise 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 SYNCbits with an image of your choice. MoneyWiz will recognise this change and start showing your avatar in MoneyWiz.
Please note that you don't need to create your Gravatar account with your SYNCbits 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@example.com but your SYNCbits e-mail is actually firstname.lastname@example.org - you can create your Gravatar account using the first e-mail and add the second e-mail later).
