GeoChicas Take Mostar is an event where to meet other women and allies attending FOSS4GE 2025 who are interested in closing the gender gap and working towards diversity in our communities. The first hour 20:00 - 21:00 is only for women and people identifying as women but afterwards, everyone is welcome! After 21:00 everyone is welcome to join!

We’ll try to break the ice and get off to a great start at FOSS4G Europe 2025 while having fun and doing karaoke! The first drink is on us! If you wish to take part in the event, we kindly also ask you to register for the event. The event is completely free but this way we can plan the activities and food better!

Adopt-a-ticket is your chance to support FOSS4GE 2024 by purchasing any number of extra tickets for the conference that will be donated to our wonderful workshop instructors and Travel Grant Program (TGP) receivers.
