I never promoted CCBill sites I have a question
 

Can you use one id for multiple programs? Or do you have to signup everytime?
Some display the hosted galleries with xxxxxxx in the link code can i just put my ccbill id in that? Can i do that with all CCBill programs?

you have to signup for each program and use the id they assign you to promote their program
best bet is to merge them when joining

Each program will have its own signup and its own set of refferal numbers for you. Sometimes if they have grouping turned on then you can use one number for all the sites in their program, if they do not have it turned on then you must sign up for each of their sites.
Now if you merge your accounts under one, you will get 1 check but you still must use seperate accounts for each program.

ok thanks.
