global:send vs global:send_message

Hey Kevin,

Just finished up the third episode, jonesing for more :).

In the screencast you use:

register_nick(ClientName, ClientPid) ->
  global:send_message(?SERVER, ...

But the downloaded code uses global:send. I’m not quite sure if it’s a version difference or something but I got errors from global:send_message:

** exited: {undef,[{global,send_message,
                           [message_router,{register_nick,"Koz2",<0.50.0>}]},
                   {erl_eval,do_apply,5},
                   {shell,exprs,6},
                   {shell,eval_loop,3}]} **

Your eagle eyes have caught an error made in the footage but corrected in the code. Obviously we’re trying to catch these before the production footage is released but every once in a while one gets thru.

I did not get any errors on episode 3. so is this code better?
