here are the details..

connect to the server, hit the console key " ` " and type this:
set skin "$$"  (with the double quotes)
goto multiplayer options, player options, and select allow downloading and make
sure you allow skin downloading
then reconnect to the server and the following should happen:

]set skin "$$"
