Today I created a community just for people connected to the Kinokabaret. Join and add your local Kino-cell as a group there (if you are a founder or organizer). Post your events (Kabarets, screenings) there, as well! This works like all the other social networks, but it is reserved for Kinoites only.
The advantage of this will be to have a secluded space and to quickly find the next group and the next Kabaret. Of course it is free of charge.
