1. we should work on english first, this is the most important if we want the manual to be really available 2. yep, one of us used in the docbook structure f the manual will certainly have to do or review this german translation. 3. i've never worked on tutorials, but some kind of initiations are already included in the manual and we could have the same for masking+clipping. i'll try to find a few hours to write this in the next days.
