I agree. I have made a similar post 8 months ago and 2 hours ago. My need is a little different. I have a repository of posts that I want to "meter out" a few a day.
The single response I received was from another member who said to simply make the post as usual but put the date in the future. Will this work for you?
It does not do what I want. I want to run from a Chron job, so I can do the jobs that a computer can't do.
If I see anything else to help you - I'll post, but I don't think so since I did a "sitesearch" of wordpress.org with google and spent hours not finding what I need.
