The foundation of your website is the web page. A Page contains text and pictures and is essentially static, that is to say it only changes when you edit the page.
As we have already mentioned, WordPress started out as a blogging platform for writing online journals, so one of the fundamental building blocks is the Post or journal entry. Posts and pages are almost identical but for one important difference. We can create a special type of blog page which contains a short excerpt of your most recent posts. This is effectively your journal. As you create new posts, they are automatically added to the blog page like pages of a journal. They are displayed in reverse chronological order, i.e. newest first, and by clicking on the title you can go to the full post.
In general you will mostly be using pages, but posts can also be useful for creating a news page, or a thought for the week/month page, with the most recent items at the top. We don’t add a menu entry for this by default for the simple reason that unless you are going to add new entries regularly, a page displaying old news just looks neglected and reflects poorly on your organisation. But if you would like this added, please ask.
Media is the generic term for everything else you add to your site apart from the text in your pages and posts. The most obvious example is images, and after you have uploaded an image then you can use it in your pages and posts as many times as you wish. You can also upload PDF files, Word documents and anything else you wish. These additional file types will not be displayed on your site, but you can provide links to them so that others can download them, for example a Gift Aid form or a club constitution.
