It's one shirt per person. If you have 5 list owners, it's 5 shirts. If you run 200 lists, it's still 1 shirt. If your spouse also runs a list, no problem, that's 2 people x 1 shirt = 2 shirts, and PLEASE don't use job vs home address to "fool" the program, it actually knows that there may be multiple orders at one address and we would rather save on postage. We were also thinking of offering free shirts to schools where kids using LISTSERV in the classroom, but this turned out to be a can of worms. If you use LISTSERV for teaching purposes and would be interested in getting free shirts for your students, and above all if it isn't going to turn into a can of worms, contact me privately and let me know how many shirts and what ages/sizes. These would be the "L-Soft T-shirt" models which have minimal advertising contents. All the shirts are premium quality, if we wanted people to wash their cars with them we would offer free L-Soft sponges instead :-) Eric
