Cyco - thanks for being my first test subject! You've discovered how the whole thing is meant to work on your own, which is great! And you are entirely correct about usage. Sign up for an account, upload your images, and go.
BUT a word of caution... the version of the site you're using is prefixed with "dev" for a reason: I'm still developing it. That's why there's so little in the way of instructions. It's meant to be intuitive (as evidenced by the fact the Cyco was able to figure it all out), but I do realize there's a need for directions. The dev version is a major update to the original version
of the site which had no ability to upload images, and had a lot fewer features in general. I've really just begun to show it off and solicit feedback, but my hope is that other GMs will eventually decide to use it for their games.
If you'd like to see how I use ditzie for a PbP, I encourage you to sign up for my demo game
. I'll run multiple instance of the game to accommodate as many players as I can. Yes, it's DnD 4e and I realize that doesn't appeal to everyone, but it can be less about the game and more about using the mapping system, if that's what you want to make of it. 4e is a pretty tactical but easy-to-play game, so I think it's ideal for what I'm doing (and, personally, I like it).
If you don't actually want to play, feel free to look through my other two
games to see how my players and I use the tool.
Also - I will probably set something up on my personal forums soon to solicit feedback for ditzie. I don't feel comfortable using MW to develop and debug a personal website I'm building, and I don't want to overstep my bounds as a member of this community.
