I have an app where I have more and more users, so far I had to create an email address for the user in Zoho Mail, then creat the same user in Creator, and then do the programming (scripting) to get the login name from them. (I have some scripts where I need the individual user, since some data based on them)

The Customer portal is something else, but how can I make this long process easier, shorter? How can I use the login name from my users in the Customer Portal to scripting? 

Other issue is still, I never know what is the exact username of them, unless I login myself and check at the right up. (but with Customer POrtal it is impossible, since the user will chose the password)

Your help would be appreciated,

Thank you, Balazs
