How do I get the wordpress logo off my site?

I installed ultimate branding for the purpose of getting rid of the word press logo. I don't have anything to replace it with yet, I just want it gone. I am training myself using my own site, which was originally a Joomla site. I want it to look like my original site, but it just looks like a poorly done blog site. I'm getting frustrated, because I am usually pretty intuitive with software and found Joomla easy, but Wordpress just seems really hard to use to create a website.
