So you'd like us to 'deactivate' your 2½ year old account, full of history and presumably somewhat well known (I do recognise that account name), for a brand new one that no one will know?
I'd also like to point out that all I can do is ban the account from the forum, which really achieves nothing, the account will still exist for using LFS online (and unlocking, if you were to purchase a licence). If you just don't want to use that name anyone, then the power is with you, simply stop using the old account. We generally don't permit people having multiple accounts here, so please just choose one account and stick with it.
