So I guess when I tried to /tell them and got an error, that meant they were on a different world? I just assumed they had signed off. There was something like "could not contact" so it was not clear they were on a different server. It seemed like I got the same response when I tried to /tell a friend that was offline. Sadness.

RE the FC part of Loadstone, the FC I'm looking at (Adamantoise Fairy Tail) says it is for beginners, but I cannot find a way to contact them to apply. Definitely feeling dumb there. But I'll try '/tell'ing their founder an see if I can catch them on-line.
