This plugin adds async messages delivery based on time or online status of the users through /defer-post and /messages-queue slash commands.

The /defer-post commands that allows to defer the delivery of a message for certain amount of time, or until the other user is online (in DMs).

• /defer-post [time] [message] - Send the message after the time has passed
• /defer-post online [message] - Send the message when the user is online (only valid for DMs)

The time can be specified in the golang format that you can see here.

• In a DM you can run /defer-post online please take a look at this ticket #123. That will send the message to the user whenever the user is online again, so you don't have to worry about annoying him while he is offline (no message, and no notifications).
• In any channel you can run /defer-post 2h Starting the deployment. This will schedule the message to be sent in 2 hours.

The /messages-queue commands allows you to create and maintain messages queues that are sent based on a schedule.

You can list, add and delete queues, and the messages in it. Every time the scheduled message queue is triggered, it sends one message from the queue. So if you have a queue with 20 messages, and your schedule is to run it every day, is going to take 20 days to send all the messages.

When the queue is empty, no messsage is sent.
