I have added a direct link to the contributor community webpage in the Discussion and Development Section on the project README and I also listed the community meetings (with links). I tested the nav links on my branch and it all works. 

I wanted to provide a suggestion to the issue I opened referenced above if this is helpful in aiding future contributors and their understanding of the communication channels. 

Thanks @ssharp0
