Any reason the plugin itself doesn't work for you? It does require you to actually click the button to create the post, although I assume it can be automated for Ghost (we just tended to make it a little more generic so it works with WordPress, etc.)
Schedule Posts request
I'm not sure if this is a feature request or a plugin request. Either way, I need a way for posts to go live when I'm not at my computer, so a method for scheduling posts to go live at a certain time would be most welcomed.
Please let me know if this isn't in the right place or if there's anything extra I need to do. This is my first time posting on these forums. Many thanks!
