I know I'm going to miss a few folks, but there are many new level 90 adventurers. Last month it was Lakland, Squidget and Oakthicket. This month's list include Mitron, Foxer, Bekkia, Ikux, Aganor and Zlync. A few folks are very close. Nizmin is at 89. Kodomo is close too so should only take another couple of months to get there. 
Just kidding Kodo. Honestly. Now don't get angry. Ouch. 
The guild also dinged level 84. It'll take a few more months, but level 90 is beckoning.
We've cleared a couple of instances - Demitrik's Bastion and Outer Vaults. I'm sure there'll be many more to come.
