Broken Links in FCC site

Hello everybody,

This is my first topic post. I just received my first certification in FCC " JavaScript Algorithms and Data Structures" and is great to have one, so I started to read about how FCC can help me to get my first job as a developer, and I found a broken link in the about page of FCC.

url text 1: browse our alumni network on LinkedIn here.
url text 2: one of the hundreds of companies
broken link:

url text: donor-supported public charity.
broken link:

I know this is not a big contribution but I think that It could be helpful to fix this links for other new readers like me.

Thanks @QuincyLarson and FCC team for creating this learning platform and community, hope to find a job thanks to you guys!!!

God bless you.
