Zoho Wiki and Zoho One

Zoho Wiki and Zoho One


I have some doubts about Zoho Wiki and I would like the community help.

1. Is Zoho Wiki part of the Zoho One package? Or it will be?

2. Can I use Zoho Wiki as an online course platform like Coursera?
      2.1 - If positive, can I have certificate, polls and payments associates for the online courses?
      2.2 - Will the atendee have it´s own dashboard and course page?

3. What is the difference between Zoho Desk Knowledge Base and Zoho Wiki? It seems they are quite similar and do the same work.

Thanks a lot
