Hi!
  I found a new name that better highlights the themes of my game.
  Basically, the game is about graduating from a school of magic in a Harry Potter-like world.
  There is a good mystery mechanic and conflicts are resolved with dominoes. One side determines who gets clue points and the other determines who narrates.
  If you want to play it on line, you can use this software:
http://www.vassalengine.org/download.php
This is free, java-based, multiplatform and games are hosted on their server, so you don't have to much with firewalls and ports.

And this module:

This module will let you use text chat, dice, dominoes, tokens and play them anywhere on the virtual table.
