Ok, my first question is..how do I speak with other people?
and I got a suggestion, I think its possible to form groups(not sure) , how about we from KH insider create one? I'm with the Vulpes o//
There are two ways I know how to speak with people. The first is under the encounter menu. On the left side of the screen, there is a bar with three tabs. Under the first, there is a chat feature, which you can use to create a message to be displayed to members on you're team while you're at the main world.
You can also send messages directly to people. If you click on a person, their name, or somehow get to their player page, you can leave them a message using the window on the left. You can also send them a friend request through one of the options on the main window. Not sure which one off the top of my head, and I can't check right now. The right one will bring up a prompt with two options, and clicking the one on the left will notify you that a request has been sent. I don't know how to respond to requests though.
Darn, I picked the bear before checking the forums

Does anyone know what to do for Story 1-4 in Agrabah? I found a door that I can talk to near the top of the city but it gives a dialogue box and won't open.
Sorry, can't help you there. I'm stuck on the same part.
Im also stuck at 2-1 for Wonderland.
