Yup, I just made Level 70 (thank you, Dugi!). The Wrath of the Lich King is loading, even as I type.

Unfortunately, I had forgotten that the Burning Crusade only goes to Level 70. So I turned in three or four (frankly very difficult) quests before I realized that I wouldn't get any experience credit for them until I sign up for WotLK.

Dag. It's always somethin'...
