You think filemaker would enforce their copyright if we made our own shirts? Pretty easy to get some embroidered polos or one-off screened shirts in this day and age.
It would actually make me chuckle if I showed up at devcon and someone from filemaker told me I had to take off my shirt.
Do you have a link to that? Don't recall ever seeing a tshirt store in technet.
If a group wanted to organize an order and FM was happy with what we were doing, I sure would be interested in buying an FBA shirt and a FM12 Certified shirt. I already have a couple of Technet shirts. As the local FMPUG Coordinator, I like to wear a FM shirt to our functions when I can.
