I am in the process of resetting up my site with CCBill. I was using AuthorizeNet which workked ok but want to give my members an alternative. I followed the readme and everything worked perfect in setting it up, however I wanted to give you 2 comments in minor problems I found that CCBill helped me fix. First in the Readme under #9, it says to enter the sub account. In the CCBill control panel it shows for a sub account 3 digits like 123. For them to receive and direct the script properly there has to be 4 digits, so instead of entering 123 you have to enter 0123 in aMember. Also when you enter the Sub Acct Type, in the CCBill panel it again only shows 3 numbers, this in aMember has to be entered as a 10 digit number, so if you see 123, that needs to be entered as 0000000123. Other then that the setup was great. I was also told by the guy I was talking with that alot of their clients use aMember.
