Where is the post id number?

that would be under the page’s permalink.
you can format permalinks different ways.

Roll over any page, post or category with your cursor (while logged in and in the “manage” area of course), and the page, post or cat_id number appears in the progress bar in the bottom of the browser.

Thanks, the rollover trick worked!

Glad it helped!

When I try this, I get the name of the page/post, not the ID number???
