Updates on BP Provide data up to date and BP Make feedback available

Hi Annette,

As agreed in our discussions last week, I rewrote the following best
practices:
- Provide data up to date [1]
- Make feedback available [2]

The corresponding commits are [3] and [4]. If necessary, I can make new
updates after having your feedback as well as the feedback from the rest of
the group.

Thanks!
Bernadette
