I received the Postcrossing cencus 2021 email and immedietly started to answer it. But in the drop down menu of the answers for the question “In which year did you join Postcrossing?”, it does not contain year the 2021. It ends in 2020. I think this is a mistake, but if it is not, how could I input that I have joined in 2021?
Yes, I faced the same issue. I joined postcrossing in 2021, but was not able to answer that question.
I left it blank and proceeded to complete the census.
By the way, it’s currently possible to answer the questionnaire more than once. I don’t know if that’s on purpose (multiple postcrossers in one household?) or not, but I figured I would mention it.
