I am looking for a solution to an issue my fellow Minecraft server friends and I have. We want to shared lots of locations of where things are. I'm sure this is a common problem. I'm interested in finding a web app where we can all log in and enter the locations of particular things in our world and then see this stuff drawn on a map. The map doesn't have to have features of the Minecraft server on it. It could be a blank white page with black dots on it. I've started created a website like this for my friends and I but I'm wondering if something much better already exists.
