Request renaming of my account

Currently I'm changing the nicknames I'm using on the internet from 'qense' to 'sense'. The reason for this is that my real first name is 'Sense', and I'd like my nicks to tell better who I am.

On Launchpad my nickname is still 'qense', and I would like to change my nick to 'sense' here as well. However, the account <https://launchpad.net/~sense> does already exist. However, it is an old account already, and it seems that the user has never done anything with the account.

I would have tried to mail him, weren't it that the domain name for his email address seems to have gone to one of those ad spamming domain brokers.
