Tips

A neat trick, is to put this single file dismiss-welcome-nag.php (not its parent directory) in the /wp-content/mu-plugins/ directory (create it if not exists) so you won’t even have to enable it, and will be loaded by default, also, since first step installation of WordPress setup!

Explanation

This, is different from the other similar plugins, because uses the filter hook, and not the action hook. Filters should filter information, thus receiving information/data, applying the filter and returning information/data, and then used. However, filters are still action hooks. WordPress defines add_filter/remove_filter as «hooks a function to a specific filter action», and add_action/remove_action as «hooks a function on to a specific action».
