This type of action is used to send out SMS or Windows popup message to one or more recipients. It has the following
type-specific parameters:
- Message text: the text of the message that will be sent.
- Recipients: phone numbers or machine/user names that will receive the message, separated by spaces. Each space-separated element is used as a phone number if it starts with a digit or "+", otherwise it's a name of user or computer in your local network. Variable references are allowed.
- Send flash SMS: if this option is activated, outgoing messages will be tagged with a special flag «alert (flash)". For the vast majority of the cellular phones it means that the message will be displayed immediately when it arrives, and it won't be kept in the phone's memory.
