Ok, i did a search and either there was no suggestion with this in it or it was to far back that i didn't see it.
But my suggestion is a wall in town that people could go up to and post small messages, such as wanted messages (ie. looking for tools, gold, iron, etc.), advertisments (dance contest, etc.), or other small messages that people think up of.
Having this would clean up some of the smaller less important posts on the rp board on this site, and be really well for trading and such. The messages have a maximun length, so they are not to long. Old messages would be taken down after being there for a set number of days.

i think this is a very good idea too

or maybe you could just make paper and write what you want on the paper and place it on walls,trees. ect

not sure what it was called but it was proposed before, as was paper,pen, writing with coal, ect. Fadaykin even made some nice papyrus graphics, which I must say were quite good. Other things like sheep skin to write on or leather were mentioned too.
