Just to elaborate on this (just incase you don't already know), W31 Yanille actually has its own friends chat channel, under the name "altar". If you join "altar" friends chat, its fantastic because you can find out immediately everybody who is hosting on that world.
You may already know this, but if you didn't then I hope this is helpful to you! I see way too many people who just stand outside of the portal saying "house?" or "altar??"
