Different areas, same guild?

Is it possible for players from the three different servers (Korea, Europe, America) to join the same guild? I'm thinking of buying this game for my little sister, who's in the UK, and I'm in Japan. I'm playing on the American servers. If it's possible for her to still join my guild, I'd tell her to play on the European servers, since people will be online at the same time as her, it'll be faster, etc. However, if it's not possible, she's considering joining the American servers, which basically means no one will be online to play with her (not that anyone's online when *I* play either...).

Can someone help me with this?

its possible

im not so sure

No offence, but I'd like a more definite answer.

Part of me doubts it, since the favor of the gods thing is in there, and it's done by area.

Indeed it is possible

grom being in a korean guild and plays on american
omg japan is teh r0x!

great! Thanks so much.

[TRUE] also has some European players, although we are on the American servers. Unfortunately, I've never been able to play with them because of the time difference

are you guys sure about that? i have heard that people on the american server cant switch to the korean server anymore, i havent tired myself, but i wouldnt want him to get his hopes up for nothing

Only Korean copy of Guild Wars can play on the Korean server I think, My European copy can only play in the Europe server or US server.

Members in a guild can be from any server, it makes no difference. Obviously they can only be in the same area, if playing in the international district or in the guild hall.

[WPG] also has members from US, Canada, UK, Germany, Israel and Australia all in the guild and on either the American or EU servers. We meet in an International district to play together. Unfortunately it limits things we can do together related to who has favor.

Could you list what the things that have to do with favor are for me? I know the hall of heroes since it's announced all the time, but is there anything else?

underworld and fissure, two of the harder areas, are only accesable to whichever distric has favor at the time, they arent required to beat the game though

Once a zone (Europe, America or Korea) get favore of the gods by winning HoH 5 times in a row, all players (ascended) of this zones servers may enter the FOW and UW.

In addition, all gods statues all over the map are activated and you can get moral boosts from them.
for example: the statue in ascalon foothills.
the lighted statues can be accessed even from international servers if one of the party members are from the zone that have the favore of the god.

People form different zone can play together in international districts, but you might have problems to find enough party members there.

You cannot enter UW/FOW from international servers. So, if your guild members are in different zones, you cannot play UW/FOW together.
