Basically, you add posts to the queue, and over time the queue automatically drip-feeds those posts into your social accounts and/or blogs.
A queue is connected to one specific social account or one specific blog.
You can connect more than one queue to a specific social account or blog, which means you can have several queues that automatically feed that social account or blog.
Let's say you create one queue that you call your "quotes" queue, you also create another queue that you call your "interesting links" queue, and you create a third queue that you call your "cool photos" queue.
You connect your "quotes" queue to your Twitter account to drip-feed your quotes at a rate of one post every 12 hours.
The "interesting links" queue you connect to your Twitter to drip-feed the links at a rate of one post every 3 hours.
Lastly, you connect your "recipe photos" queue to your cooking-related Twitter business account, because you're only going to add pics of prepared meals into that queue, and you drip-feed the photos at a rate of one post every day.
Optionally, you can tell the system to drip-feed the posts only on Monday through Friday, between 8:00 AM and 6:00 PM (these days and times are fully configurable per queue).
Now all you need to do is make sure that there are posts in those queues. The system does the rest. You don't have to spend any time on scheduled dates or times.
If you want, the system will email you when a queue has run dry, so that you can again add posts to it.
You can also configure the queue to always recycle published posts back onto the end of the queue, which means the queue will never run out of posts.
Posts are drip-fed from the queue in the order they were added, in other words, first-in-first-out.
The drip-fed posts automatically appear as scheduled posts in posts list (Posting, Scheduled Posts) just before they are published to the social accounts or blog.
