Hi Jacabraham, I see what you mean.
When you say
Using the Editor tool, I attempted to adjust the "Powered by WordPress"
do you mean that you have edited the footer.php file of the theme?
And if so, did you create a childtheme first? http://codex.wordpress.org/Child_Themes
Sorry to ask, but since you mention that you are new to WordPress, you may not know that this is an essential first step if you want to start editing the theme files.
Let me know and I'll try to help you.
