I'm wondering if a person may help me.
I've added a category known as 'Case Studies' within the publish administration section.
Can there be in whatever way to include a meta box within the 'add new post' screen for just the posts within the 'Case Studies' category?
You'll find a great tutorial here.
If you're searching to personalize Meta Explanations or Key phrases for any publish, you should think about the All-in-one Search engine optimization wordpress plugin: http://wordpress.org/extend/plugins/all-in-one-seo-pack/
