I'm officially confused..... you have a picture of a rugby game but you're talking about football - must be a cultural thing! I've not heard of tipping competitions, so maybe that's something else that doesn't translate into British English?
LOL - yeah...and even within Australia it's confusing as "footy" is rugby league in Queensland but is Aussie rules in Victoria. And some people have started referring to soccer as football just to add to the confusion!
Tipping is like a gambling thing - each week you pick which teams you think will win and at the end of the season there's a prize for who ever got the most.
I see! You're nearly as bad as the Americans, calling everything by the wrong names ;)
So the answer then is no, I'm not entered in any footy tipping competitions!
