How & where to Login?

Hello

(Sorry if I appear weird, as I am totally baffled using this service)

1. While signing in, the ID used (Admin ID of domain, to be used for login at Zoho) is nowhere to be seen/used.

2. The Contact email (once verified) appeared on top, used to show as "logged in from" ... strange

3. Next I input Admin email for this account and password.

Now I am not sure how and where to Log In. (I opened two accounts here, as I was not sure I understood correctly understood the procedure.) Everywhere it shows "Sign In" and no "Log In"!!!

I want to go to Control Panel and delete Users but don't know how to navigate.

Any help possible?
