Hello!

Please help me in my website built by WordPress

I am new to WordPress and a certified newbie.

My current theme has a built in home page that automatically displays new posts in the latest order..

Here are my questions:

1. I want to create a "Home" Menu that when clicked directs to the built in home page by my theme.
How do I create it?

2. How do I assign a post to a certain website page? I tried creating a post but it automatically appears at my built in home page.

3. How do I create a page that will not display in the "Menu Bar" ? I tried creating a page but it automatically displays as a Menu.

Thanks in advance! Hope someone will courteously answer my questions.
