Fixed Sponsors and Site Map

Fixed the sponsors listed, adding Datto, LinkedIn, and UofR to the list. Put these three on the rotating 5 on the landing page. There was also an issue where there are sponsor emblems that get hidden when viewing on small devices. The proper behavior is for them to show up at the bottom of the list, moved out of the way, but there they weren't done right, fixed that.

Also after removing the scholarship page, the link was still in the site map in the footer, so that was removed.

Poke around my members space to see it live.
