User Email Database – phpmyadmin

Hi all. I am a new WP user and would like to ask if anyone could teach me as to how I can extract user information from the tables in my database.

So far I have created three users other than the admin user account and I would like to know 1. where all the information keyed in during user registration such as email and username are stored 2. how to get to this information and 3. how to retrieve this information. The thing is that I want to use the email addresses and names of the users to compile a mailing list of sorts.

I have browsed through the forums and learnt that I should use phpmyadmin to view the tables in my database. However, I am not conversant in the use of phpmyadmin and thus found it extremely difficult to understand the documentations I found on the website. Any layman type of explanation would be most helpful. I would deeply appreciate any help that anyone can render on this issue.
