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.
Running around with StreetComplete, the app sometimes tells me to leave a note instead, which I do. Short time later, I receive an email that another person has resolved my note. That's nice, but wouldn't it be better to do it all on my own?
I think I need a more powerful Editor for that, and installed Vespucci. Now I'm scared to break things. What are the next steps, how to proceed?
When you open openstreetmap.org, on the right-hand side there are some buttons. Click the one that looks like a stack of papers (it'll say "layers" when you hover it) and there will be an option to enable a notes overlay.
In the editor on the site (called iD) you click the icon on the right that looks like a line and a square (Map Data on hover, or press the U key) and it will have an option to show notes as well.
Generally I leave notes alone for a week or two to see if the user intends to resolve it themself (I talk to myself a lottttt in notes while I'm surveying) but if it's still there after that, I do my best to resolve it.
