I have the supernova theme and in the menu for supernova it has an area under setup where you can set up your site like you talk about. Try going under your theme settings. hope this helps
Have a great day!

I recommend you fix your menus so they don't stretch onto two lines through the use of custom menus.

You can add these custom menus to organize your top menu in any way in which you like, as well as create sub-menus (for themes that will support this). You can also use these custom menus to add within your side widgets on your website (within your sidebar).

Here is a tutorial on how to create custom menus:

I use custom menus on all of my websites (over-ride that default menu). It allows much more control and organization....both good things!

Can't answer the question - because I'm not a techie - but I have got a word of advice (that you didn't ask for) is that you ought to be posting - longer articles. When people come to your site they are looking for information, solutions to problems, ideas etc - but it's quite hard to do that if you have posts with a selection of links and no added value. Sorry - I know you didn't ask - so feel free to ignore :) Beverley
