Academic systems and cultures vary widely between countries, and answers will depend heavily on this context.
I have come across many questions, where the country has not been stated – presumably because it had not occurred to the poster that this information was relevant. Now one can of course ask in the comments to add this – but this causes a delay and gets a bit repetitive.
Is there a way to encourage posters to state the country which is relevant? I was envisioning something like a drop-down menu when asking a question, or at least a line reminding posters that it might be relevant.
