Today, I discovered a fantastic plugin called Sidekick. They offer you a step by step guide like how to add a page or create a post.
They said that it's a "Real-time, voice-guided WordPress training and support straight from your dashboard."
I tried it and I am very impressed by how it's easy to use and how you can learn quickly how to use the dashboard, how to create a page or a post... etc.
If you are new to WordPress, it's the must have plugin to learn how to do things inside your dashboard...
Play with it now:
