In WordPress, you can write either posts or Pages. Pages are for content such as "About," "Contact," etc. Pages live outside of the normal blog chronology, and are often used to present timeless information about yourself or your site -- information that is always applicable. You can use Pages to organize and manage any content.

In addition to the generally required "About" and "Contact" Pages, other examples of common pages include Copyright, Disclosure, Legal Information, Reprint Permissions, Company Information, and Accessibility Statement.

Posts are entries that display in reverse order on your home page. Posts usually have comments fields beneath them and are included in your site's RSS feed.

Uploading files can be accomplished through the WordPress interface. No FTP access should be needed.

Video Uploading

We strongly recommend against uploading videos directly through Sites @ Georgia Tech. Instead, upload your videos through MediaSpace, YouTube, Vimeo, or another video streaming service.

Note: If you are having problems uploading files with the default Flash uploader, you may want to use the Browser uploader instead.

1. On the Dashboard menu, click Media and then click Add New to display the "Upload New Media" page.
2. Click the Select Files button to open a dialog box.

To change the privacy of the content, follow the directions below.

Privacy

To change a post or page to be private or password protected, please follow the directions provided by WordPress:

URLs of Your Pages

WordPress will automatically create a URL part ('slug') for your page as soon as you complete the name of the page/post title. 

Changing the URL of Your Pages

To change the URL part (also referred to as 'slug') containing the name of your Page, use the 'Edit' button under the Page title on the Edit screen of the particular Page, accessible from Pages tab of WordPress Administration Panel.

To create a post/page:

1. Log in to your WordPress Administration Panel (Dashboard).
2. Click the 'Posts' or 'Pages' tab.
3. Click the 'Add New' sub-tab.
4. Start filling in the blanks: enter your post title in the upper field, and enter your post body content in the main post editing box below it.
5. As needed, select a category, add tags, and make other selections from the sections below the post. (Each of these sections is explained below.)
6. When you are ready, click Publish.

To create a teaser or a preview for your post for display on the blog page, follow the directions below.

Process

1. Edit the post you would like to trim down.
2. Locate the area on the story you would like to place the 'Read More' on.
3. From the editor box, select 'Insert "Read More" tag'.
4. Save your post.

To edit a post or page:

1. Log in to your WordPress Administration Panel (Dashboard).
2. Click the 'Posts' or 'Pages' tab.
3. Click the 'List' sub-tab.

Subpages allow pages to exist as child-pages of another page.

Create a Subpage

1. Go to Administration > Pages > Add New panel.
2. In the right menu, click the "Page Parent" drop-down menu. The drop-down menu contains a list of all the Pages already created for your site.

4. Add content to the subpage.
5. Click Publish when ready.

When your Pages are listed, the Child Page will be nested under the Parent Page. The Permalinks of your Pages will also reflect this Page hierarchy.
