This is your unfriendly-going-to-be-pissed treasurer typing.
Please pay your t-shirt and gathering money.
Then I wouldn't have to nag so much.
Another thing, it's only security, stage, PR and PnP that have helpers right? Don't forget to collect your helpers t-shirt money. Make them pay on the spot. And give the money back to me.
Thank you for your co-operation.
