Hello and welcome! 
The idea of this bingo is to count the countries we met by sending postcards to and receiving ones from during 2021. The starting point for counting is January 1st, 2021.
I hope that this Bingo will be interesting and you will join it 
You can get a Bingo by either sending or receiving cards to or from 20/30/… countries during 2021 (after 1st January ‘21 and before the 1st January ‘22). In this Bingo there will be more than one one price: for 20, for 30, for […] different countries.
Rules:
~ Only official postcards sent on postcrossing.com are counted towards the bingo.
~ Only postcards registered sent and received after 1st January 2021 and before 1st January 2022 are counted, travelling or expired cards are not. For example, if a postcard is sent on 2nd January '21 and received on 6th January '21, it is counted. If postcard is sent on 28th December '20 and received on 5th January '21, it is not counted.
~ Please update your lists regularly by editing your first post.
~ Please include the updating date and postcard link. Posts without links will not be included to the rankings.
~ Please, don’t post your lists several times, because I will only count the first post.
~ If you have more than one Postcrossing account, you may play them separately, but not combined.
~ Every time when someone gets a Bingo, all the other participants will send her/him a postcard as a prize.
~ When you have a Bingo I will contact to you for asking your address then I will send it to your partners.
~ If you have any questions please send U2U to me or just post here your question.
Hope that you will like this Bingo
Have fun! 
So, let’s count sent and received cards in 2021 together!
