REMINDER: Bring a printout of your proof-of-payment email

From What The Wiki?!

Hey ho,

first people arrived on-site and the buildup is starting... with people packing for WTH, just a reminder: if you have paid in advance, don't forget to bring a printout of the email Jacco has sent you.

See you soon!
