This is how BMSTA's FNF works:

Every friday night at around 6:30-7:00 pm (pacific time, Oregon, Washigton and Calafornia) we all pile into a server to kill eachother. The voted winner of the night gets to choose out next game from our list (HL, OP4, TFC, CS, L4D, DMC, Ricochet(if you choose this ill kill you,) Hl2DM, Condition Zero, all Half-Life 1 mods, Zombie Panic! Source, Doom 3 (I think im the only one who has it but it has good DM) and Doom 1-final) They can choose to host the server or not. If for some reason FNF can not be held on Friday, we do it saturday. If it is a Team Deathmatch, the winning team gets to choose the game.
