Unfortunately NCsoft screwed up my pre-order registration, so now I have to zero out my whole account and start over. It's all good, though - I was planning on starting all my heroes from scratch anyway once I started up my own account, and the two I already created (Colonel Snark and PastyPaleWhtBoy) are only around level 2 so they're easily taken care of. Once I know my chat ID it'll be easier to stay in touch with everyone. :)
