One thing that I think would be amazingly helpful is an exit message in towns. As you cross the border of a town "You are now leaving/entering [town name]." This will help scouters know where they are without having to constantly use /rgi and/or Flint. How difficult is to use? No clue, but I've seen it on other servers (not mentioning any names) and it was extremely helpful.
We used to have it, and it was removed. http://www.ecocitycraft.com/forum/threads/72692/ There was a discussion on whether it would impact performance, with kukelekuuk00 believing it would. His last post in the thread is quoted below.
