If anyone has any ideas on how to make multiplayer in FO3 work, please write down what you think.

The poll has nothing to do with this forum which is for FO3 mods and if you want to discuss multiplayer there is a topic here - http://www.gamesas.com/index.php?/topic/1112031-fallout-multiplayer-discussion-thread/
