i have one old account, but i just registered a new account today with a different email address. Is that ok
I dont know if Adwords has a referral program, But it should be fine as long as you didnt use your old account as a referral Edit: But then, It's google. Who knows.
First off i don't like using my old account, beacuse i had some problems with getting a refund from google, so i was very angry with them and i was ready to sew them, but everything turned out fine. So im not really into getting back with my old account, it brings back bad memory's. Ill see if i can delete one of my accounts from a different computer.
