[aur-general] Sign offs for community-testing

Greetings, With the latest kernel update to 3.4.2 i got a message from pacman that vhba-module needed kernle < 3.4 (vhba module is needed for cdemu ). I installed vhba-module from community-testing which is build for 3.4 kernel and have encountered no problems. How can users/non-developers help with sign offs for community-testing ?
