I received an email stating that I can apply the rest of my guild to be in the Vanguard beta. They just want the FORUM usernames and email addresses of those who want in. If you want to join my guild in the beta, please post here or PM me your VANGUARD forum username and email address and I'll add you to my list.
I was also told that this was made public as well. I don't have the link as I am at work, but somewhere on the Vanguard you can apply your own guild if you want.
Anyway, just thought I would give you the heads up. This is a great opportunity to those who want in the beta. Again, just PM me if you want to be added to my list. This isn't a guarantee you will get in, but its worth a shot.
