Star Wars: The Old Republic will want to head to the game's official website this morning and have a look at the latest news blurb. It seems that phase three of the pre-launch guild program has begun, and BioWare says that "any guild that meets the pre-designated criteria [will] be transferred into the game for launch."
You'll also want to make sure that at least four members of your guild have pre-ordered the game (and redeemed the associated code). BioWare notes that it has removed the requirement for the guild leader to log into the website and confirm an active guild.
Finally, each guild page has been given a status indicator that shows the number of member pre-orders as well as whether or not your guild meets the deployment criteria. More info is available via the Guild HQ page and the official site.
