@mariatta these things are one of the main roles of "Pythonbrasil" - the Brazilian org equivalent to the #PSF - it takes a 10% of any donations, and that is enough to cover operational costs, and then it works as an Umbrella org through which the money for most Python events in Brazil goes through.
I've even used Pythonbrasil to fill this role when organizing the non-directly-related to #Python #Libregraphicsmeeting in 2017
