First log into sandbox.hi5.com with your hi5 account, and you'll be prompted to register as a developer. Once you're finished, you'll see the new developer console (below).
Create your first app and enter the url of your OpenSocial xml.

Once you've submitted your app, you'll see a link to display your app working inside hi5 and also one to refresh your xml from its location.

Click the View About Page to see your app in action.
Your OpenSocial app will appear in the new hi5 Gallery on sandbox. We'll be adding new features to the console over the next few weeks and allowing you to publish your apps to the live Gallery from here soon, so stay tuned.
Hack hard,
Dave
