The original question dealt mostly with permissions and reminded a problem with a program called composer only as a subtle issue that might possibly be associated with the permissions issue (just to sharpen the question). I asked the question as a total newbie in Linux and Ubuntu.
Someone have changed my question entirely including the title, to how he saw fit, and than answered on this other question a seemingly-sadistic, too much mocking answer, and in the covering of a honest technical answer. His answer even got a 1 dislike and I commented on it from my POV.
I really love this site, and I want to stay here, but this really gave me a bad taste. I have flagged the answer but no one seems to take care of this in the last hour or so (I guess the mods here are always on).
Please consider bringing my question to its original state and anything you would see fit with the answer; I think in any case the edit control should be re-examined in that context and I hope no one here will see this suggestion as audacity.
