Nostalrius Begins - Quality wow vanilla realm (1.12)

because I was stupid and impatient I created 2 accounts,
I could just not use one (fine w me) but in an effort to keep realm population 1 person more accurate id love to delete my duplicate account.
how should I go about this?

the realmpopulation is not counted on the amount of accounts created or on the amount of users created.
but more on the users that are logged in.
so having a second account that you do not use is not a big deal!
