Greetings all.

I am interested in creating a fantasy map of a text MUD that I am staff on. While there are many mud-mapper programs, I am looking for two things:

#1 I am looking for a collaborative online program that can be worked on by many people across the country. Ideally a gigantic grid with the ability to change the color of square and label them.

That's so I know what all is there in relationship to everything else. Since the MUD is gigantic, the more staff to work on the map the better.

#2 I am looking for a good software program to create the fantasy map on afterwards. Checking the forums here will be one of my first steps at that stage.

Any ideas?

Thank you so much.
