For any content that you create in your Mighty Network (including Quick Posts, Articles, Events, Polls, and Questions), Network Moderators and Hosts can schedule the content to publish at a later date.
How to Schedule a Post
To schedule something to publish later, just click on the down arrow next to the Post button > schedule post.
When you schedule a post, you'll also see an option to decide if you want to "Notify All Members" as soon as the post is live. If you choose to not send a notification, your post will simply show up in the feed and members will find it via search or in the Topic you've assigned the post to.
How to Find Your Scheduled Posts
You can find all of the posts that have been scheduled within your Mighty Network by going to Your Profile > Scheduled Posts.
On that, page, you'll see a list view of all the posts that are scheduled to be published. To edit the post or change the schedule date and time, just click on it to open up the editor.
