I've noticed that thing taking the most time to explain ( for each person, and many people ask about it) to new players is trade system. I think popping window with all informations from trade passwords to empty trades and trade security would be very useful. Newbies will be able to read it peacefully without text moving down, they will have A-Z info in one place (now they are asking at least two times. 1st password/union room, 2nd empty trades/how to evo my kadabra?) and people trying to help wont need to write everything on and on.
