hmm the easiest way to make an account is to edit one of the existing ones.
if you downloaded the account db-files which contains alot of accounts, edit them(but only the id, when i edit pass, it says, incorrect pw)
if you use the clean ones (both by silkbotter) search in the account db files from above and add the user id+pw+... manually.
if you want to create a char you just log in with your account and create a char and edit it in the db(search for "making a private server video tut"-threat and watch the 2nd part
