What posters do people have in their ICT suites / offices / corridors / etc? Our ICT suite has some rather out-of-date posters on "How the Internet works!", and that's about it. We could do with some nice, professionally produced, cheap posters on subjects that are actually useful. In particular, Tom Newton's thread about passwords got me thinking - I could do with a poster on "How to Choose a Secure Password", for a start. Does anyone know of a good source for decent educational posters, or is there a bit of a gap in the market here?
