Hi, 
We’re building site for a local school and have a few issues, the site is temporarily here:

Home

The issue we have are:
Linking the logo to the home page – where is this specified? 
Icons not showing in Top bar menu – we want to add some custom icons for each external link. I’ve added the icon files, but they don’t appear in the drop down and then either way what show if I select an existing icon.
Thanks in advance for your help.
Ed
