Hi Steven, thank you for commenting. Now I'm a little confused with the terms.

If I correctly understand menu paths are the ones created from hook_menu and often related to a callback function, right? Let's say user/login and user/register in user_menu(), right?

What's what the return value in a _submit function, the destination parameter and $form['#redirect'], a url, right?

Please let me know what I'm missing in order to correct the article and be as accurate as possible.

Regards!
