Main.asc file

Hi, Maybe I am just dumb to ask this question. I am using FMS. I am building a chat application. I have created two files one file is to bootstap peers.
And, the second file I created is to distribute introductions across servers in a peer registry. My question is…am I required to create a third ActionScript communication file that allows clients to communication with each other that accepts or rejects a client to the server etc etc? Or, does the two files I have created allow me to do this?
Thank You
