take a look at this:    http://www.myspace.com/shareonmyspace  

 Are you using firebug to debug?  Is there an exception you're getting?   Are you using external iframe?  I noticed that you reference opensocial,  which isn't defined in the iframe js.You would need to reference MyOpenSpace.MySpaceContainer as you're doing in your other call.    

The port number does need to be 80 or 8080 iirc.

 Looks like an error is happening when the site tries to load that app profile page.  Maybe the profile or app got corrupted somehow.  You could try re-creating the app with a new email address, and see if that solves the problem.

Users who add the onsite app have granted access to it, so they shouldn't need to take the additional step of granting permission to the MySpace ID app as well.  Your iframe will be called with the viewer_id/owner_id, as querystring params which you can use to identify the user.  You can make server to server SDK calls to fetch their ...

It looks like there are really 2 apps here, 198404, an onsite app, and 198403, a MySpace ID app. After the users add the onsite app, they will have to also "log in" using MySapce ID.  I'm not sure what our policy is on this, but it's not an ideal flow.  The app also asks for an email address, which needs to ...

 Hi,   Yes, what you want to do is possible.  You can get the list of friends, along with their display names and pictures using the call to get friends.  You won't need to make individual calls for each friend's basic profile info. There's also a filter on HAS_APP, along with a HAS_APP field, that you can use ...

The external iframe Javascript does not have the full opensocial container.  It only has postto capabilities.   You'll need to make server-to-server calls using one of the MySpace ID SDKs to get viewer/friend info.  

 I'm guessing this happens when you try to create an app, and it's complaining that it needs a number or punctuation symbol in the password.  There's a bug that the error isn't getting translated into a proper message.    

 Hi,  Sounds like the MySpace ID approach is right for you, since you just want server-to-server updates.  We don't have a gallery for MySpace ID apps now, so even if you publish, people aren't likely to find it. I don't see any reason that you couldn't leave the app in development mode indefintely, either.
