I have to admit that I don't do much offline things to support Paul. Living in Sweden it is kind of hard to reach a lot of Americans, so I asked myself who I could reach. Luckily, I'm studying English at the University of Stockholm and the professors at the English department are mostly English and American. So I've mentioned Ron Paul in a some of the essays and other types of written assignments that we have had. I've also talked with one of my lecturers after a seminar and I wrote "Google Ron Paul!" and "Ron Paul for president!" on a bit of empty space on our last big test (yes, it is probably not very effective, but at least it's something).
Great thread, by the way!
