 You can schedule sending messages to actor that will be acted upon in the future. To achieve that you can use the following methods on the [Actor System](./actors/actor_system.go):
 
 - `ScheduleOnce` - will send the given message to a local actor _**once**_ after a given interval
-- `Schedule` - will sendd the given message to a local actor at a given interval
+- `Schedule` - will send the given message to a local actor at a given interval
 - `RemoteSchedule` - will send the given message to a remote actor at a given interval. This requires remoting to be enabled on the actor system.
 - `RemoteScheduleOnce` - will send the given message to a remote actor _**once**_ after a given interval. This requires remoting to be enabled on the actor system.
 - `ScheduleWithCron` - will send the given message to a local actor using a [cron expression](#cron-expression-format).
