It looks as if most people are going, so those that are over there will not be playing here while their characters are gone. Because they'll be outright gone.
We don't go over there until the 5th, and we'll be staying a full two weeks, not coming back until the 20th. It's been decided that logs that are started over there will be allowed to continue if people are a bit slow. Like with new challenges, once it's over, you can continue with the logs you've got, you just can't make NEW ones.
