Have you ever worked with a client where you are trying to customize the WordPress back-end experience for them? Maybe you added a custom dashboard widget, removed menu items, or even created custom write panels. Well Greg Kerstin (@graphicagenda) was working on a project where he wanted to modify the howdy text in the WordPress admin bar. Normally it says Howdy, Username. He was kind enough to submit a snippet to us in which he shows how to change the howdy text and replace it with Welcome.
