I've only been here for one, maybe two customs, but maybe a newbie only slot for customs? Could be they've never won a custom or never tried?
I"m not sure if they do that already or not, since like I said, I was only here for one or two and that was AGES ago.
And I love the buddy-system idea! Maybe even buddy-type games? But with the newbie getting the prize out of the "winning team.
