Translation incomplete

Hi,

I’m working on the german locale (also the formal version). What I noticed, is that some strings can’t be translated:

1.) In the overlay that appears the first time Projecthuddle is presented to a user the explanation text below “Willkommen!” (I wonder where is this translated, as I didn’t touch it :-o),

2.) The “okay” button on the same modal

3.) The button “+ Comment” in the toolbar

best regards Stefan
