finally, it is here: The riot-os tag on Stackoverflow. (https://stackoverflow.com/tags/riot-os/) It took a while to reach the rank to create a tag, but I reached it on saturday. My first action was to create a tag for RIOT. Unfortunately it took some days to get it approved. I already submitted a tag description, but it will probably also take a while until it gets approved. I will also continue adding the riot-os tag to old posts. There are a few of them (https://stackoverflow.com/search?q=riot+os) Since Stackoverflow has a huge community of developer and also a good rank in every search engine, I encourage you to start using Stackoverflow for your question with the riot-os tag. Watching it on a regular base and answer some question is also helpful. This will increase the visibility of the project and may get more people involved in it. It might be a good idea to promote it on our channels. (Twitter, Readme, to name a few) Every help is welcomed. Have a nice week.
