A few years ago. Seeker printed up a bunch of Dream Views business cards. He may even still have a few laying around. We have a Cafepress store set up, where you can get T-shirts, also. If I find some time, I may make some sticker designs, too. Be a nuisance, and slap them over urinals and on gas station pumps.
I think the more the merrier. It definitely takes the right type of introduction to get people to realize what lucid dreaming really means. It is a little mind bending and impossible sounding at first.
