There is! @nerdtopiade put out this post a few days ago :)

We have a german channel on our Discord and we would love to add a polish channel as well! Expanding our curation team is part of the process of helping these communities grow on Vimm.

Thank you for your feedback! We will do a better job at promoting these events in the future.
