[Plugin: Aleph] Adding users' views

Hey threre, I’m using the Aleph plugin, it’s very good and finally I managed to solve almost every task i needed.. just one thing is obscure for me:

In the readme the author says that you can create custom users view with custom slugs and query.. that’s exactly what I needed, but it seems that i don’t understand how to do it.

He says:

After the plugin is loaded, you can add new lists/views using a special function called aleph_register_view:

add_action('init', 'my_aleph_views', 100);

function my_aleph_views() {
    aleph_register_user_view('view_slug', 'My User List', 'user_key=some_meta_key');
}

The question is: WHERE I have to put that code? in my theme’s functions.php? I’ve tried every file but nothing works.. 🙁 please help!

thank you.
