So, it looks like we will be setting up shop on the Juyo server! If you signed up for the guild on the SWTOR site before the lockdown, you should see a mark on your server selection screen for Juyo. Anyone else will just have to find it manually. :)
My character Ra-Mos has been created and the Guild is available. You should be able to do a WHO on Polyjedious to see if anyone is on. Any officer can invite you and anyone can be invited!
Also, check out http://buy.swtor.com/us/#optional-game-add-ons for information about the authenticators. I can't stress how important having your account secured can be. Please think about picking one of these up. Hopefully a mobile app will be available soon too if you don't want to deal with the physical "fob".
