still brand new here...just setup multiminer and im using a pool called bitcoin affiliate network

On my multiminer it has spot for worker name and i put my screen name.  on the BAN website it has an area for me to "configure workers'' and add a suffix.  do i need to do this?  Or is it going to automatically go into my account? 

Also it's my understanding that the flow is as follows:

1. mining is math
2. miners do math
3. i get a percent of the work my miners do in bitcoins
4. bitcoins go to my wallet
5. i take over the world
