I'm back from vacation and have some news for you:
We have now landed the last two strings that we're going to do as
late-l10n for 3.1rc1 - just two changes post beta 2.
That means, that we're complete and open for you to sign-in for
Thunderbird 3.1 RC1. I've just opened the milestone for sign-ins.
Please go to the l10n dashboard and sign-in for your locale once your
locale has gone green.
We will accept sign-ins until Monday 17th May @ 23:59 PDT, which is
one day later than we have previously announced.
If you have questions or need help, feel free to ask here or send me
