How to Check Which eBay Account Flybuys Are Tied with?

Ok, like most ozbargainers I have multiple ebay accounts. I've hooked flybuys up to one of the accounts but can't remember which one. I've gone all through the account tabs etc in eBay, but I can't find anything mentioning if it's hooked up or not. If I try to hook it up it just says that flybuy account is already associated with an eBay account.

Anyone know how to work it out?

Thanks :P
