Hi there! I am getting close to finishing up a website (mentioned above) and am hoping that I can get some of these last questions answered. I will ask them individually as things progress.

The first thing is about the default social icons in the Spirit theme. I would like to position them on the Homepage somewhere and to fit the right hand side of the main navigation on the global menu on other pages.

I would like to include 5 icons total. 4 being links/icons for Twitter, Google+ Pinterest, & Youtube. The 5th icon/link I would like to be custom (meaning a custom icon/image I have with a custom link)

Thank you!
