I had two accounts on PokerStars for a while. The first one I created years ago, back in high school, and I never used it for real money
(doesn't really matter I think). Then last year in fall, I started playing poker again and completely forgot about the old one. With time, as I uploaded some money, I stumbled upon information that you cannot have two accounts, and then I remembered of my old account.
I sent an email to PokerStars, saying that I have an old account, which I do not use anymore and that I only want to play on this one for real money. They later deleted it and let me keep present one.
I think you should choose the same option, if you have one.
