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 was looking forward to the PPV tonight, never having bought a TNA PPV before. The crappy Raw on Monday night really raised my hopes for this show -- I didn't really expect too much, but at least it wouldn't be as boring, right?
