I didn't even know there was an internet presale this early (usually it's the day before tickets go on sale IIRC), but I just found out and the password for the WWE sale is DANNYJ. Hope this helped and that this hasn't already been announced here, I looked but didn't find such a thread. Go to fordfield.com and click on the WM23 logo. It's supposed to end at 10:OO PM tonight.
I missed the main event because of softball but the rest of the show was solid. TNA has done some bad stuff lately but I think Lockdown was such an abomination that they finally realized they needed to pull it back some.
