New Clan

Go to the Clan-o-Mat on Coruscant, and follow the directions there.
Use the <petition> command to let the wizards know. A wizard will be in touch, asking how many players you have lined up for the clan, what planet you want it on, and other questions.
If your clan is approved, your clan will be created, and you will be able to build the clan hall.
If and when you want to add an alternate exit, or shuttle locations, you can use petition to get approval and have a wizard set them up.
