It really sucks. I was a confirmed host then was switched to inactive finalist for some reason. No idea why, I did everything asked.
Seriously pissed off. 78 confirmed guests so far to what looks like it might be a Windows 7 RC party as I can't cancel as people will still be bound to turn up. Anyway since they were the ones that royally screwed up I'll have to send them the invoice for any expenses for my party (and yes I have checked with my sisters boyfriend sister who's a lawyer, and they are liable for any expenses as they were the ones that made the error and also mentioned I can invoice them for my time)
