Hi. I'm checking out wpmudev on a 2 week trial. I've had a WP site built for my business and since then I've been maintaining and editing it with basic knowledge and trial and error. I'd like to make use of the different plugins such as Hummingbird and Hussle over the next couple of weeks to see what is possible but I'm struggling a bit with the language used in the descriptions. There are some specific things I want to learn how to do though that I could really use some help with. I want to know how to make the top navigation menu bigger and how to alter the page background colour.
