Hi,

I've set up groups, workspaces,, created documents, etc - great fun!
Where I really struggle is inviting people. Whenever I send an invite for workspace, I get the message that it is not a
valid email or ZohoID.
How do I need to go about this?
The documents and workspaces I have set up need to be shared with various people (that's why I signed up for Zoho)!
They cannot just be sent? Contacts need to register first to be able to work on documents? in  workspaces?

Please reply urgently;

Thank you.

Gregor
