Just saw some important improvements in google calendar.
1. They have brought in the capability of creating events right in the gmail in the drop-down menu. I wanted that and had created a post on google groups regarding that but I see that it has been integrated for long.
2. The SMS facility to inform about events has been brought to India -- Airtel provides that and I am happy. Airtel has always led the communication market in India and have been providing the best of services at the best of prices.
