change 404 page
Instead of Pounce and the latest tweet on the 404 page, can you put some useful information, such as where to report a broken link, and maybe a link to some of the useful navigation hubs, like the A-Z department list? The tweet (and even Pounce) is fine, but it's not really helping users who are lost in the new pages, and we've already gotten some complaints from prospective students and parents about it. Adding a default broken link instructional paragraph before the tweet would do wonders.
Each site in the latest theme can have a custom 404 page. We have developed a template for release later this summer.
