Collaborating/connecting with other ZOHO users.

Collaborating/connecting with other ZOHO users.

While I am considering purchasing ZOHO-One I have a question regarding referring ZOHO to friends and professional contacts (free-lancers) I work with.

Is it possible to collaborate and connect (through Cliq, Connect, Meeting, chat/channels (in ZOHO-Mail), etc.) with other ZOHO users who have their own account (not associated with my organisation)? This way we can create a network of ZOHO users. This would add extra value and benefit to recommending ZOHO.
