Anyway, I wouldn't really recommend scheduling actual posts. I have done that before and it was a disaster.
The addons that do that, generally won't have issues with threads, but when it comes to replies, there are known issues, where a post inside a thread is posted after reaching it's scheduled date, and all the replies after that, ends up showing up as being created before that reply. That, or other weird things of the like.Scheduling posts can be a really good thing - cause people aren't always around to post. I suppose the thing is to do it right. How exactly did posting become a disaster?
