I was thinking that the advertising would have to have the stickyness of a stamp. Or a possiblity of a 'post it' flyer type thingy. Either way, its an untapped well because people read advertisements when they have nothing better to do, not only that, the beauty would be that they would have to find a bin for the damn things so they would probably end up reading it on the way to the bin.
hey, its for your own benefit. For a guy living in a totally different continent your german is good, considering alot of people in the south of the US barely speak english right.
