at present, the only thing in the url identifying the wall is the name. if someone changes the name, the url will break if it has been sent to anyone. therefore, either the old names have to be stored as well as the current one, or the id of the wall has to be used in the url as well.
this way, if someone is linking to a wall that has had the name changed, the url will still work, if it only based on url.
