Everything #OpenStreetMap related is welcome: software releases, showing of your work, questions about how to tag something, as long as it has to do with OpenStreetMap or OpenStreetMap-related software.

There are many communication channels about OSM, many organized around a certain country or region. Discover them on https://openstreetmap.community
https://mapcomplete.org is an easy-to-use website to view, edit and add points (such as shops, restaurants and others)
https://learnosm.org/en/ has a lot of information for beginners too.
Unfortunately the OSM website has a limit to how many it can show you at once and it shows the most recently updated ones, so you can't see how many unclosed notes still exist.
One of them is over five years old and requires on-site verification, so I know what I'm doing this weekend!
The built-in tools on the main osm website are really limited. My favorite 3rd party tools for managing notes:
I wish Notes Review let you filter out a user. One person makes a lot of notes in my area, and many of them are ones that are low-priority to add. It would be nice to be able to see everything else. I know I can do this on StreetComplete, but it would be helpful to be able to do it on desktop as well.
The mapcomplete.org/notes theme does that, and has some other fun features as well
