Zoho allows open registration - How to restrict?

Hello folks,

Installed Zoho VO and i'm really digging it. As the sys admin for my company, we've been looking for a solution just like yours which doesn't require it's own mail daemon but uses an existing mail server. Only thing which is a problem that i can see is on the initial login page it allows for anyone to register. How can i eliminate this? As the administrator, i should be the one creating accounts and setting permissions etc. We certainly don't want any Tom, Dick or Harry out there making accounts.

Reason i ask this is we wish to build a server and put it in our colocation rack with a public IP so anyone in our organization can gain access to it.

Many thanks!
