Hello Danubius.
I've also stopped participating in this club, as in July 2022 I've sent 4 packs and received nothing back. I've posted a comment here in the discussion group about it, and some members replied it was fair as I had more received than sent (that was due to the first months of this club, as you certainly know, when you opened "new" slots for the more active members to allow for more simultaneous exchanges), but no answer from you.
Even if that was a policy of the site (and defined by you), as least an explanation would had been great then! Just saw this thread and remembered to repost the situation. Thank you.
Regards
