Change favicon in DotNetNuke portal

Times have changed in the DotNetNuke world since this question was answered. Now, the favicon is much easier to change.

Go to Site Settings underneath the Admin menu, and scroll down to Appearance. There should be an option to upload a new icon, or use one currently on your site.
