I've been playing Arcanum through GameRanger with some friends, and we're trying to get the party system to work. Please help.
I read the manual carefully and the instructions are vague at best. I searched the internet extensively and the best I could find was to type "Join (Player's Name)" I've tried all possible variants of this that I could think of. I tried clicking on the player first, right clicking the player first, nothing seems to work.
If anyone can help, please let me know.

Just to make sure, the host of the game set it to a cooperative game?

Yes. We thought of that after a while so we exited and re-started the game. I made sure that Co-operative mode was selected, but still no luck.

Thats a bit odd its backwards from what the manual claims it to be as far as I understood the manual anyway.
