Please note the changes made on May 12, 2009:
- The isPremium() call has been removed from services
- Documentation for getAdvertisements() has been updated to reflect the new strategy for displaying ads
In particular, "premium" is no longer something understood by the core. Instead, to hide the ad panel, all currently displayed services need to submit null or a 0-length array for their advertisements. When this occurs, the ad panel will be hidden.
