You have to hover over the Post links inside WordPress, which reveals the "ID" in your browser's status bar. An easier way is to install this plugin, which puts the information back into WordPress for you. In my opinion, this is a feature that is lacking in current versions of the WordPress framework.

Great to hear that! Thanks Sam~

This is a great plugin, it's very common for plugins to ask you for ID's, this plugin makes you wordpress experience a little easier..

Thank you.
