Argh – if I don’t write this down I’ll never remember it – and Google searches brought up all kinds of weird data, not related to what I was trying to accomplish. I just wanted to get rid of the some of the links – for instance, the one to WordPress.org – that appear on the main page of a default WordPress installation. Here’s the deal: open includes/default-widgets.php. Search the text for “wordpress.org” and you’ll find the links – just remove what you don’t want….. Theoretically, I guess, you could add links. Anyway, that’s where the data is stored.
