Hi therese
I replied to a number of messages that you sent a while back via the forum feedback contact....you would only be showing as a visitor if your browser is blocking "cookies" from NeuroTalk. That would cause the system not to recignize your log in. As you have posted this it seems it is allowing you full access now?

if Doreen is trying to register an account with the same email address as you have then she would not be able to, but as long as she uses a different email address for her account, there should be no problem in her registering, as long as those "cookies" are allowed.
