I want to connect my neighbourhood in some way, but I don’t know how to handle this privacy friendly 🤔

we want to connect to coordinate … lets say some gardening. we can handle first information via email, but afterwards it gets messy for the organizer. the neighbours don’t care about privacy at all as far as I know so Element/Matrix won’t work. and most of them don’t have 'media literacy skills. should I give in and forget about a coordinated talking ground outside of neighbourhood meetings irl?
