MODEL CHARACHTERS?!?!

i have question. I have 1.2.3 and you know at www.esf-world.com and do you know under models and do you know how you can download new character skins and put them on as the regular characters.. well i do it and i put what i am supposed to I.e goku.mdl but its a rar file and the original goku file is a mdl file.. so everytime i join a server a new goku file creats insted of letting me use the new character.. how do i put the new character on properly?

well first of all. u gotta unzip that .rar file then put the model file to models/player/goku folder if u have a new goku model

First get winrar at www.rarlabs.com

after you install it use it to extrat the RAR file and youll ger the MDL file
