Changing the URL of a project in Launchpad

Hi,
I've just registered a new project (VAET) and have made a mistake on the project name (put my name instead of the project name). I've already changed the "display name", in the change details page of the project, but the URL doesn't seem to reflect this change. As it has been said, "Regarding to some postings here, it's common to ask the launchpad admins for this, is it right?," (Question 46264 ;) ).

So i think i may ask you to change the url. The project URL is https://launchpad.net/fgianni and i like to it to be https://launchpad.net/vaet.

I there is a new way to do this myself, i'll be pleased to do it, just told me.
Thanks in advance for your next answer.
