In West End in Brisbane, (australia that is for you foreigners) they have erected three post up boards for community messages. Imagine a ten by six corkboard with a wrought iron surround (artistically done of course) They were extremely useful for advertising alternative concerts and the unspoken rule was that you could take down a poster to make room for yours once the date had expired. An interesting thing is that the wrought iron work at the bootom of the board consisted of several loops, into which people began inserting rolls of A5 flyers for events. It would, in hindsight, have been better if these holders were incorporated into the design. Hope that all helps.
