WordPress is in a continual state of development. This is great because the functionality of the site grows and adapts with the latest technology and tools. The Plugins are updated quite frequently. You will want to check periodically on these plugins to make sure they are updated. It is a simple process as this video shows.

In the dashboard select Posts.

Select Add New.

Enter the Title, Text, and/or Coding in the appropriate fields.

In the right-hand menu, select the appropriate Category.

In the right-hand menu, enter Tags under Post Tags.
Tags are on-site keywords that identify the post content.

Either publish the post, select edit just above the publish to schedule a time to post, or save draft if you want to work on it later.
