We haven't done any flyers at all, just a library display (did anyone want to check that it's still up? It got taken down within a half hour of being put up, twice on the same day last year, due to a misunderstanding between library staff)
The plan is that we set up tables in Centerplace and talk to people about Free software, and hand out disks. We skipped the advertising this year because our expensive newspaper advertising last year was very dissapointing and highly ineffective, most of the people who turned up had not even seen the newspaper advert and I think only two people turned up because of it.
Planning for this is online at
