I am not much active user here but I once (more than a year ago) asked a question on Computer Operating system which was well received by this community. Recently I posted another one and am thinking of creating tag for computer operating system but not sure, so I asked it to moderator who is available in chat. He suggested me to post a question on Meta.
So, I am posting this question to cover the computer operating system and computer hardwares in general. Would it be useful to create a tag dedicated to operating systems? Or would it be more useful to post this type of questions on Retrocomputing.SE as suggested in comments?
