Guild Wars 2

I was trying to play with a friend on a British server (I’m in America), but I couldn’t find the “join in” button when i selected his portrait in the party window. Does this feature not work?

The “Join in” button is only used to join in the same overflow.
You are talking about guesting but as far as I know it has not been implemented yet.

Some more info about guesting: http://wiki.guildwars2.com/wiki/Guesting#Guesting

If your party member is on another server than you are, then you will have to be a little patient. Guesting – visiting other servers – is going to be an option eventually but it isn’t ready yet

Oh, okay. Does anyone know when guesting will be implemented?
