Change 554, 555, and 556 to the IDs of the fields that you want to make conditionally read-only.

Blacklist any IPs and prevent entries from being created.

If you're using a data from entries checkbox field which pulls values from a form that creates posts, you can display links to these posts (in a View) with the code below. Just use [x link=true show=id] in a View, email, or confirmation message. Replace x with the field ID or key.
