Trouble seeing sibling's character

ok, my sister and i want to play guild wars together, so we each bought a different copy of guild wars and i have it on my computer and she has it on hers, well even though we have seperate copies and computers, we can't see each other , but we can still whisper to each other, why is this? does anyone know?

Check what districts each of you are in. And did both of you choose the same worlds?

When you're in town, you have to make sure you're in the same district as her. In the upper left hand corner there's a drop down thingy that will say, for example, Ascalon City (District 13). Ask your sister which district she's in and then use the drop down list to select her district. They have this system so that towns don't get overly crowded, but you can go to whatever district you want provided there aren't too many people there already.

ok thanks
