V40K Battle Finder has been Taken Down Due to insufficent members using the tool.
There was over 200 members signed up but only a hand full of people were registering for battles and noone actually confirming a battle.
Maybe this is due to lack of instructions on how to use the site, i dont know, becuase there is a help link on how to use the site under Help. So unless there is a demand for this to be put back up, which you can request on the Vassal40K website, battlefinder will be no more.
Thank you for your support.
