[Plugin: runPHP] Compatible with 2.7?

Does this plugin work with WP 2.7? Maybe I’m just missing something, but I’m able to figure out this step in the installation:

“Create a post and check the “run PHP code?” checkbox to enable PHP code to be dropped in to your post”

The checkbox doesn’t show up anywhere when I create a new post. I’m using an admin account which can use runPHP by default, and I’ve checked the box in options to activate runPHP.

Thanks!
