Tarvos, this channel is accessible from any and every server; its a cross-server chat channel that exists for all monks on all servers to chat (and we even tolerate Bruisers =D). Just type join Crushbone.Allmonks and you'll be in. To speak in the chat use /#
except you have to put in the correct number in the place of /#. When you join the chat you'll see a message that say "You have joined 'crushbone.Allmonks' (#) and thats the number you use 
There are non-cross-server monk channels on every server as well. These are listed as "Qeynos_Monk" in the "World Channels" under Chat Options when you right-click a chat window. Unfortunately, since class channels are not automatically joined once a character becomes a new class, most people don't know they exists.
