Okay, found the places button. I do not see Welcome Island on it. When I click on London City Community Gateway, I get a msg saying:
"You cannot teleport back to Welcome Island. Goto 'Welcome Island Public' to repeat the tutorial."

Plan C: I start out and I'm supposed to cross a bridge (to Welcome Island?) and I found that I had a terrible time trying to stop the avatar from moving. Somehow, someway, I got teleported out of there to Ferry Terminal and Infohub, Barbarossa.
