Sending to server is faked.
You want to use [Arguments](http://androidapi.xamarin.com/?link=P%3aAndroid.App.Fragment.Arguments) member to store the data. Currently the args field data is lost should Android recreate the fragment.

This would be the foolproof way of doing it:
```c#
private static readonly string UserMessageArgument = "com.toggl.timer.user_message";

// ...

public AskPublishToAppStore (string userMessage)
{
    var args = new Bundle ();
    args.PutString (UserMessageArgument, userMessage);
    Arguments = args;
}

// ...

private string UserMessage {
    get {
        if (Arguments != null) {
            return Arguments.GetString (UserMessageArgument);
        }
        return null;
    }
}

// ...
```
