Please confer with the authors of the document(s) in question if you feel it

Yes thanks, that's what I had in mind, but this should be cleared in the
FAQ,
if you need it to be done, I can take the time to clarify this point and
make
an addition to the FAQ, or dou you intend to do it yourself (because of my
broken english) ?

Is there a document somewhere which explain what to do to submit such
modifications ?
