Start by watching this How to post video (3 minutes). Posts are for information that is updated regularly and that accumulates. They appear in the order of their publication date, with newest first, so if you want to change the order of posts, edit the publication date. If you’re working on a post that isn’t ready to Publish, you can save it as a draft. Once you have published your post, if you make further changes, save them by clicking the Update button.
When creating a link to any document or website outside this site, be sure to edit the link to open in a new tab.
To show only part of a long article on the Home, Minutes or Archive pages, you can show just an excerpt. Use the “more” button if using a text editor, or the “dotted hamburger” button if using the Visual editor, to insert the break where you want it.
Adding pictures and docs to the Media Library, for insertion into posts and elsewhere, video here (2 minutes).

Create an NGG gallery with the Gallery link. Then publish it by creating a new post. Use the little green square icon to insert the gallery in your post, and check the Gallery category. You won’t see the images in your post on the administrative back end where you write it, just a snippet of code or empty box will appear in the back end, but the images will appear on the front end of the website.
Very short intro here (<2 minute video), more detailed intro here (17 minute video).
Pages appear similar to Posts and are created and edited similarly, but are for information that changes less frequently and doesn’t need to be archived. Editors can update them as needed. Click “Pages” on the left-hand menu to see which parts of the website are pages.
ALWAYS make a full backup of both fiies and database before updating the version of WordPress! Backing up is also wise before updating plugins. It can also be useful to Google the recommended updates to discover known problems, before proceeding. Only knowledgeable users should do updates. Don’t be tempted by that little red “Update Now” button!
