I am beginning the process of placing a Stack Overflow T-Shirt order.
Please refer to the two meta t-shirt questions to see proposed designs (or post your own), but I think we're going to have to go with something simple and basic to please everyone.
At the moment, I am thinking a large-ish copy of the logo on the front of a plain white (but quality!) T. Sort of like the above, minus Konrad's amusing recursion joke. :)
Yes, there will be Super User and Server Fault t-shirts as well -- and probably black versions of all the above.
If you have experience getting T-shirts printed, please share any tips or recommendations on the process. I do expect our order to be a fairly large one...
