Find the welcome message you want to change (e.g. "welcome-message-wall-user" is refers to the automatc welcome message posted to a user's wall by an admin), and then click on its red link: it will bring you to an edit page with preloaded text. Modify the preloaded text to what you want it to read, and then publish it.
