A Smart Queue allows you to create settings for how to schedule posts added to it. Currently, you can set the following rules:
The number of minutes that must pass between the posts which are posted from this list.
The time of day when posts are sent out from this list.
The days of the week posts will be sent from this list.
The text to be added to the end of posts before they are sent. (Tags will be added until there is no room left.)
The percentage of randomness for the interval between posts. (i.e. if you set the Interval to 10 and Randomness to 20%, the interval between posts will be randomly selected between 8-10 minutes.)
If you think of any other condition you would like added, please let us know.
