I check G&FH at least once day. This morning a new question (Getting birth certificate of German born in Romania in 1895) was already closed as a duplicate because it asked for birth records in a particular country. (The answer should address time-frame and region, not just the whole country; the accepted answer is too limited, in my opinion, to be used for all cases).
Last week, a question on World War 2 occupations (German Soldier in WWII) was already closed when I saw it, because it was assumed that it could be answered by the excellent answer on German military records.
In both cases, I think the moderators jumped the gun. I left comments, but I suspect the OPs won't be back after seeing the closures. I know comments are considered transitory, but they have been useful. That the question might be re-opened after edits is not well-explained.
Should there be a minimum time period before closure to allow other users, perhaps more familiar with the particular subject, to assess the question?
