I haven’t posted here since a long time now (too many things happened during the last weeks)
However I was active in building current snapshots of Firefox, Thunderbird, SeaMonkey, XULrunner and so on.
While preparing a current trunk version for Sunbird 0.3a1 I found that localization (and some other stuff) isn’t really integrated as it is with FF and TB. So I’ve decided to take some time getting this into better shape and to move localization stuff into the l10n repository at mozilla.org. The current status is in bug 267981.
