There might be more requirements, this is just quick thinking, and
its only
me speaking, not yet the rest of the team. But I'm in favor, if its
implemented with care.
IMO we do not even need a web app for this. We can solve this with a
git
repository where only DDs can write to. DDs would list usernames that
should be approved in a text file, one per line. It
would then be easy to change our user review script to fetch that
repository and read the hints from it. git gives us logging and
traceability for free.
