Translation updates to Ubuntu Alpha2

[Simos Xenitellis]

Hi All,
We (Greek team) translated fully ubiquity and ubuntu-slideshow-ubuntu
by around the 19th Jan 2012.
When testing Ubuntu 12.04 Alpha2 (see
http://www.flickr.com/photos/marios-zindilis/sets/72157629203902429/ )
we noticed that some of our translations did not make it in Alpha2.
https://translations.launchpad.net/ubuntu/precise/+source/ubiquity/+pots/ubiquity-debconf/el/+translate
https://translations.launchpad.net/ubuntu/precise/+source/ubiquity-slideshow-ubuntu/+pots/ubiquity-slideshow-ubuntu/el/+translate

How can we find out whether our translations were missed or whether
there is a mistake on our side.
We would like to test as early as possible that all messages for the
final 12.04 ISO are complete;
what's the preferred way to test?

Thanks,
Simos
