Launchpad Package Maintainer change

[Lanoxx]

Hello,

who do I have to ask if I want to change the maintainer of a package
that is registered in launchpad.

The package in question is tilda:

    https://launchpad.net/tilda

The registered maintainer is "Ira Snyder" who has not been maintaining
the package for several years. I am the current debian maintainer and
would like to take over the package.

Kind Regards
Sebastian (lanoxx)
