-Keep your stuff close, best tip not to get things stolen. Don't be too paranoid though, just keep an eye out.
-Buy tons of stuff of me

I will probably be selling Flash Saggitario's + Launcher Grip's for very cheap on the day. Along with even possible Beat Lynx.
-If times get awkward because you don't know anybody just break the ice with a battle etc. We're all friendly here

-Erm....Give me money is a VERY good tip
-Keep the combo you're going to use in the tournament secret. It need to be some real hush hush business or people will plan against you

-Have fun
That's it!
EDIT: Oh yeah, dont forget to bring at least £10. 3 or 6 for entry or passport, the rest to buy my stuff. If you don't see anything you like, buy me lunch or donate the money to me not a charity
