You know when you go to add new post when logged in to the admin area and there is on the right hand side a bunch of boxes with headings like publish, tags, categories...
How can i make my plugin add one of those little boxes on the right hand side to save some settings for that post for my plugin?
I am trying to make a custom permissions system so that I can create Subscriber user groups so that I can then go into a particular page or post and check checkboxes within my custom settings box to say which types of subscribers are allowed to see that page or post.
Your help is much appreciated.
This is my first useful wordpress plugin.
