Please increase my ppa space

Hi,
I'm keeping a PPA called KDE-backports (https://launchpad.net/~grimp/+archive/kde-backports) that has the goal of having always the last fix release of KDE (based on the major-minor KDE version released on the version in consideration) (ie: karmic ships 4.3.2, I will always have in it 4.3.x KDE packages). As far as I know this is the only repository with this characteristic. Could you increase the space of this repo at 3gb, please?
Thank you
Fabio A Locati
