hello there

you know these mods you are asking already exist,but they are part of the sourcemod aplication.

with an addons for sourcemod you can see a little message saying who is black & white(incluiding name and survivor: nick "gambler") even one saying if the tank is already dead.

the other one well it lets you recharge the chainsaw but with fuel cans,though i installed it i never use it/see it working so i dunno.

i hope this will help ya,if not pm me

Well, it sure helps.

heh im sorry i didn't said anything worth,it just i forgot where did i download the sourcemod,thats why i said to pm me if that dont help,cuz i may re-upload it in mediafire if you need it that badly.
if not just google it i think you may find it quickly
