Why do we have news stories and posts?
We have news stories and posts to give you a way to post time-sensitive content on your site. The advantage of using news stories or posts for time sensitive content, instead of just updating a page on your site, is that they are archived and can be referenced. However, these are optional features that should only be used if you will regularly have updates.
Is this WordPress? If so, why does it look so different?
Zuse is built on top of WordPress. WordPress can be customized, and we have heavily customized WordPress to fit our needs.
Why is search showing old content?
Our search function uses Google search. Google regularly indexes our site, and when we make changes to our site, they aren't updated in the search until the site is re-indexed. This can take up to a week.
