welcome to the boards!

now i dont want to burst your bubble per say but id strongly recommend against using your fathers account unless all the account info is the same as yours most importantly the names. you will be reported for being a haxor and apparently the first thing they do is check account infos. so it would be highy likely youd try to log in one day to two perma bans...

anyways if you have that all sorted out then good luck and have some fun!
