Here I had a discussion about to mark the headline with the tag [Solved]: Rpi4B Raspbian 10 buster Adafruit-blinka Installation Problem [Solved]. I remember that one of the moderator has written for some time in an other comment anywhere not to do this, instead accept the answer. But I cannot find it anymore. So I looked for a policy to this in the Help Center but couldn't find anything about this. Also searching here on metha I cannot find relevant matches.
So my question: is there a policy how to handle marking headlines with [Solved]? How should this be handled?
