TNA Wrestling

Ok, now I'm a bit of a Johnny Come Lately when it comes to TNA so I have a few questions. (I didn't really start watching TNA until Samoa Joe debuted)

I'm watching Nevermore: the Best of Raven and I'm wondering when did TNA start using the 6 sided ring?

Last night's primetime special only drew a 0.9 rating, according to Wrestling Observer.

Disappointing.

Is anyone else annoyed that you cannot but TNA PPVs online in the U.S.? I live in a dorm at college so I don't have access to PPV, and I don't know anyone around here with a box to do so. Yeah sure I could *cough*download*cough* watch it later, but I would like to see the show as it happens sometimes.
