New servers have been added to the list! We started with one yesterday and quickly grew to over a half dozen!  At this time they are all Order realms, with all but one Type being Core based:

We are pleased to announce the addition of new servers to our Realm Population Bonus. As explained previously, for one week, these chosen servers will bestow divine gifts upon the designated realm to help swell their ranks and give them the power to try and turn the tides of battle. Players who join the vanguard will receive a 20% bonus to renown and experience!

We've also updated our own list in the forums.  To view the complete list at The Herald, click here.
