What's the preferred alternative to Google Maps' **review** function? I loved leaving reviews, pictures and miscellaneous info on Google Maps, but obviously want to turn away from it.
As an example, where can I leave a review for the local library here, to let others know how the process of getting a pass was, what the work room is like, where you can leave your bike, where I can drop a few photos, et cetera?
I know OpenStreetMap exists, but where and how do I actually submit my 
️ information? And are there other, maybe even better, alternatives, open source?
