Just popping in a week ahead of time to say good luck to all for next week. I can't go next year, so I'm free of the weeks of stress through to T-day.
Handful of tips which have always seen us get tickets..
1) Get the ticket site up ONCE in DIFFERENT browers. So one in Firefox, one in Chrome, one in IE etc. Never have two tabs/windows of one browser type
2) Activate an autorefresh on the page, to refresh every four seconds. Once you're in you don't get kicked out on a refresh but you should be able to turn off the autorefresh easily enough anyway
3) And the obvious one to have all details in a word document so you can copy and paste over
I hope all your group gets up and tries, rather than staying in bed and thinking you will sort it....
IP / location means nothing. We've got tickets on home connections, work connections and a 3G mobile connection in Belgium before. It's luck - but also about maximising your chances with multiple people operating multiple browsers.
