I really like the idea of a sign system. Perhaps each sign has a 'name' [like 'Milepost 1', 'North Hydlaa gate', or 'Warning!'] which appears for all to see like a pet name.
Then the Description is there for when you look closer, [Like 'this way to Magic shop' or 'Beware of Tefusangs in the area!']
With signs, there would be a more easily rocognisable trail for people to find things at. Such as have signs named 'Street' which have descriptions with the street name on them, these could be types set up only by GMs and nobody can name a sign 'Street' except a GM. It would help new player find things. Then landmarks like the fallen stalagtites in the fields or the giant stalagmites could have GM approved names with 'Landmark' signs.
Then removable signs would be good for players who want to set up shops now and then, could tide us off until we can buy buildings of our own.
