Zoho Docs and Google Drive are good tools for collaboration on projects.
No advanced skills are needed to have before using these two tools.
An email address will be needed to register for Zoho Docs and a Gmail address will be needed for Google Drive.
I would recommend Google Drive as it has better features.The following is my comparison of Zoho Docs and Google Drive.
