I use WordPress as a CMS for my company web site. Around 100 pages with a blog integrated into it.
I handle press releases as "pages" instead of "posts."
I can schedule a new release to go live overnight using the scheduled publication feature, but can't find a way to schedule the publication of existing pages that link TO the new release, like the home page and main news page.
The best I've come up with is creating a new version of the page with the links added, publish it, and then revert to the most recent version until I'm ready to go live...at which time I'd have to publish manually.
