Involvement in providing timely information, and historical background *with
references and translations*, would be better.

Otherwise you could see current changes in contentious areas, argued about for
weeks or months, by parties with political stakes, before being approved.

In which case a group like this would still have to handle the practical matter
of getting timely changes distributed instead of arguing about politics.
