That bulletin board outside the Shaw's in Porter Square is pretty amazing. After a long frustrating day of trying to find places to hang flyers, and having relatively little success, I stopped off in Porter before going home. I posted a couple of flyers, and went to buy a cookie. Less than ten minutes later, I passed the board on my way back to the station, and 2 potential customers had already taken my name.

Thanks for the pointer to the Tufts library. I hadn't thought of going through that kind of official channel, because I'm not a member of the Tufts community. But there is probably somebody there I can ask.
