Half the links didn't work for me - and the site was pretty confusing. Essentially it just looks like someone would submit high quality vector artwork so a bunch of people can have it printed from arcaderenovations.com - I don't see the incentive for the person doing the artwork since they are basically creating a new product for someone else's company
Even a free copy wouldn't be much of an incentive.
I don't want to sound too critical but there it is. And of course I'm not opposed to doing some work so a lot of people could benefit - but not so someone could take that freely made artwork and sell it for profit.
(current t-shirt contest excluded, obviously - those proceeds will go to this site
)
