ok, confusing.. you should add those extra parameters into the docs.. as it still only says

addbot [skill] [team] [name]

for those who read this later, this works (notice, no square brackets):

addbot 45 5 0 5 Bot1-45
addbot 75 5 0 5 Bot1-75
addbot 45 5 1 5 Bot2-45
addbot 75 5 1 5 Bot2-75

random personality, random model, 45 and 75 skill levels, 2 on each team, obvious names

thanks for your time
