I meant to reply to this a day ago, but I forgot about it. Anyways. What you can consider is using the build in reward-essentials plugin to accomplish this. Make a group, and then make a rule in the rewards for >= add to group.
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!
