Theme advice...

Dear All,
I am building a website of quote-based posts sent by authors. Now I have seen this website www.insegreto.com that has the look and feel and features I am looking for. Could you please advice me on a wordpress theme that could support this? Main features:

  • responsive
  • neat and clean
  • embedded log-in/registration features
  • Social sharing posts
  • Multichannel approval posts (e.g. notification via email, whatsapp,…)

Thank you
Stefano
