On the Cell Phone, there is a boxed button for Chat and Help. The Help menu is already accessible from the links on the left (on the building). I feel the Help button on the Cell Phone could be removed.
Also, on the Cell Phone, there is an E-mail button towards the bottom of the phone, not in a box, just an icon. I feel the Chat boxed button could be moved next to the Mail icon on the bottom of the Cell Phone also as an icon… Perhaps another window could pop-up with a sideways Cell Phone (kinda like when you open your Tablet)?
I think this would help more people realize that there actually is an in-game chat room. I was also thinking one of the Activity Logs on the top or bottom of the game could host a Chat dialog too, instead of having 2 Activity Logs. Or maybe make another tab labeled ‘Chat’ on the bottom Activity Log?
