I have recently signed up for Zoho and I have been able to login with no problems at all.

However, I would like to add others users to my account and to do this, I need administrator rights. However I am the only user in my account (I opened the account and I am using the user that I opened the account with) and I do not have administrative rights.

How do I either:
a) Add a user with Administrative rights to my account
b) Change my account to have Administrative rights

Just to clarify there are no other users in my account at the moment, just me.

Many thanks in advance
