To be honest, so far the issues buy etc have only been with Ticketek (no surprices there) and not the Nix fault.
Trouble logging on, getting it to recongise renewal prices instead of new prives and credit card failing are all Ticketek.
Not sure how much the Club can influence Ticketek with the issues they're having? Problem would appear to be Ticketek's computer systems. I'm fairly sure Ticketek haven't turned to the Nix and said "Yeah, nah. Our computer systems are complete kack and the whole thing will be a disaster yet again this year". I'm also fairly sure that the Nix would be letting Ticketek know that they're less than impressed with the chaos. Again.
No problem lobbing grenades at the Club, when it's justified. In this case, I'm not convinced that it is.
