Kiwi usually is on during the weekends. He didn't make it this weekend for some reason, probably is on holiday.
-If you don't reach him through the forum, send him a private message it'll deliver it when he gets on.
-Worst case scenario you sign on to Korea and then go international districts just to avoid lag.
-If you know Kiwi's in-game name you can put on your friends list right away and get a hold of him when he comes on to play GuildWars too as its across the servers so not like he can be on one server, you on another and you all don't hook up.
Anyway, hope this was a little informative at least.
