if you could make, so anyone can use this by typing into channel !calc , for example !calc 4+2*sqrt(4) , this would be the greatest script :)

I think you should edit this script so you can set like max filesize and file types allowed, or else this isnt secure at all.

Can you make that you dont have to add team but you type !add and it adds yourself? Like 1x1 support.. and also for Melee or CSDM.. that when adds like 4 or 8 peoples you have to play CSDM (deathmatch) - everybody plays together - Free FOr all, its like Counter - Terrorists can kill Counter -Terrorirs and Terrorists, and Terrorists can kill Terrorists and Counter - Terrorists.. and then when mach is done you type !losers nick and nick (2 peoples go out)
