You are our 1st member living in Poland, but you will find 2 groups here that have Polish involvement: FEST & probably also Storytelling in Middle and Eastern Europe.
FEST is a group both here online, at the link just given on their name, & at conferences. The acronym FEST stands for “Federation for European Storytelling” and their conferences have been attended by over sixty representatives of nineteen countries: Poland, Bulgaria, Canada, Denmark, England, Estonia, Finland, France, Germany, Greece, Holland, Iceland, Ireland, Italy, Norway, Scotland, Sweden, Switzerland and Wales.
The 2d & newer group, Storytelling in Middle and Eastern Europe, had its 1st conference this past year. Their Facebook page is also available in addition to their group here. The group only mentions Austria, Hungary and the Czech Republic, but they also mention the countries of Middle and Eastern Europe. Knowing Csenge Zalka, the group creator, I'm sure she will gladly welcome you,too, so by all means go to their group page & to her page here.
Additionally you will find 2 education-related groups that may interest you. Besides the many specialized groups, with nearly 1800 international members, you will find general discussions in the forum, & may also find interesting member blogs & videos. Be sure to also try out the search box at the top right of each page here, as it's a great way to find people & topics mentioned here.
Welcome to your international storytelling family!
