I'm trying to find a way of adding a single checkbox to one of the existing options pages, most likely options-reading.php programmatically. Unfortunately, I haven't found any good references on this. Any thoughts from the community?
I just did some searching and found this in the codex:
Here is the link to the codex http://codex.wordpress.org/Function_Reference/add_settings_field
Looks as simple as choosing the right slug like 'general' to add an option to the general settings page.
I hope this points you in the right direction.
